Molten Chocolate Cake


   (I apologize for the out-of-focus picture. I am learning how to use a new tool to take these pictures)

When I look back at the list of food that I have cooked and documented in this blog, I realized most of the dishes either have sentimental value or trigger a specific memory. I think this is what makes food special. Just like music, it triggers neurotransmission in the brain in a way that is still a mystery.

Molten Chocolate Cake is one of those dishes that brought back memory.

I don't remember when was the first time I had molten chocolate cake but I do remember one memorable occasion sharing molten chocolate cake with wonderful friends and family at "Finale Desserterie" (Cambridge, Mass) two Augusts ago.

History books documented that famous chef Jean-George Vongericthen invented this dish many years ago after pulling the cake out of the oven too early.

I finally get around making molten chocolate cake recently and I am very pleased to share the experience with you.


Ingredients (6 servings of 1/2 cup size ramekin)

One stick of unsalted butter
6-9 ounces of dark chocolate (I used a 72% cacao dark chocolate)
2 eggs + 2 egg yolks
1/4 cup sugar
Pinch of salt
2 tablespoons of all-purpose flour

Instructions (some of the lines are copied verbatim from Jean-Georges' recipe that has been circulating everywhere)

1. Preheat the oven to 450F
2. Rub butter on the inside of the ramekins, lightly flour the ramekins and tap out excess flour. Set the ramekins in a baking sheet
3. In a double boiler, over simmer water, melt the butter with the chocolate (break into smaller pieces first). Once the chocolate and butter have melted completely, mix it well and make sure there is no lumps. Set the mixture aside to cool down to room temperature.

 

4. In a separate bowl, beat the eggs, egg yolks, sugar and salt until the mixture turns pale yellow and thick.



                                  I love how the light reflects off the melted chocolate

5. Slowly add and mix (original recipe uses the word "quickly fold") the chocolate mixture into the egg mixture, add the flour during this time. Once everything is mixed properly, transfer the batter to the ramekins. Tap the ramekins to make sure that the batter sits evenly.




6. Bake the cake for 6-7 minutes. If you have lights in your oven, you can take your cake out when you see the outer layer of the cake sets.



7. Let the cake cool outside of the oven for 1 minute, cover the cake with an inverted dessert plate and reverse the ramekin (beware of hot ramekins). Wait for 10 seconds. Slowly remove the ramekins.

8. Voila!  serve immediately. 


                             The finish product with a dollop of homemade whipped cream


                                                 Is it molten inside?












                                                    No!!!  Explanation bellow




Although this cake wasn't exactly a molten chocolate cake, the core of the cake was very moist. Eating a warm, freshly baked chocolate cake is truly and purely an enjoyment. There is something magical about the smell of the kitchen when the cake is being baked. I baked 6 cakes for a party of 5 and we have to fight for the 6th. "Hunger Game"-style!


Here are some extra after-thoughts:
1. If you look at most of the published "official" Jean-George recipe, it says "bake for 12 minutes". I baked for 11 minutes because I was impatient. Turns out 12 minutes is absolutely too long. Most food-bloggers who documented this dish baked their cake for 6-7 minutes. Hence no molten chocolate. Easy fix!

2. Many places also suggested that you can make the batter a few hours before, store it in the refrigerator and warm it at room temperature prior to baking. I am a little skeptical about the integrity of the batter (especially when beaten eggs are involved). I made the melted chocolate butter ahead but the egg mixture right before baking.  Perhaps someone can share their personal experience.

3. If you are uber-health conscious, read no further and consider yourself warned:
a) 1 stick of butter (8 tablespoon) between 6 cakes, which is 3/4 tablespoon of butter in each cake
b) Half a chocolate bar in each cake
c) and finally 2 grams of sugar in each cake

Macoroni and Cheese


 

I am not a food historian but if there is one dish that can be claimed as a traditional American dish, macaroni and cheese would be one of them.

I can think of one unique mac & cheese experience. I had leftover mac & cheese at a friend's place (at least four years ago) and I found out that his roommate was a waiter at Blue Smoke and he would sometimes take leftover mac & cheese home. I was at lost of words and vowed to go to Blue Smoke for fresh mac & cheese. 4 years have past and I finally had Blue Smoke's mac & cheese sometime around last November. The mac and cheese at Blue Smoke is very creamy and very cheesy yet not heavy at all. Go figure.

After sitting on a recipe for 3 months, I finally got around making mac & cheese. My main references are Martha Stewart and Alton Brown's recipes with my own modification as usual.

Ingredients

4.5 cups of grated cheese
(approximately 20 ounces or 1.2lbs of total cheese). I used 50% white sharp cheddar and 50% Cabot.




half a pound elbow pasta
half a yellow onion, diced
3 tablespoons butter
3 tablespoons flour
3 cups of milk
Panko bread crumbs
1 bay leave (optional)
Pinched of cayenne pepper powder or paprika (optional) 
many recipes asked for mustard but I did not use it in this dish.


Instructions

1. Heat the oven to 375F.
2. Boil a pot of water and cook the pasta to al dante according to the manufacturer's instructions.  At the end of cooking the pasta, rinse it under cold water to stop the cooking and drain the pasta completely.
3. Melt the butter in a large pot using medium heat.
4. Add the flour to the melted butter and keep stirring until all the lumps disappear. This thing that you just make is called a roux, which is a thickener. 
5. Stir in milk, bay leaf, onion and paprika.
6. Simmer this at medium heat for about 10 minutes until the sauce thickens. Remove the bay leaf.
7. Stir in 3/4 of the cheese and make sure the cheese are completely melted in the sauce.
8. Season with salt and pepper. (I made a mistake here which you can read about at the end)
9. Mix the cooked and drained pasta into the cheese sauce.
10. Transfer the cheese-coated pasta to a pyrex dish or any baking dish. Cover the top of the pasta with one layer of the reaming cheese and sprinkle the panko bread crumbs over the cheese.






11. Baked for 30 minutes until the panko break crumbs turn brown.
12. Let it set for 5 minutes before serving.






The MOST challenging part of making this dish was grating the cheese (I want to thank the Hayes for lending me their cheese grater). Took me about 30 minutes to grate all the cheese and my arms were sore at the end. I wonder how the mac & cheese would taste like with grated cheese from the grocery store. There may or may not be any differences but I like the fact that I can grate the cheese of my own choosing.




I was fortunate to have two food-tasters and they gave me encouraging feed backs. I warned them that my mac & cheese was too salty and they agreed. When I was salting the cheese sauce, I decided, unwisely, to over-salt it expecting the pasta to balance the saltiness. Nope, it didn't and it was a big mistake. You should salt the cheese sauce to your exact preference. Lesson learned.

Another problem that I am yet to figure out how to overcome is this - the pasta came out over-cooked after the baking. Which begs the questions: should I under cook the pasta first? or should I increase the baking temperature while reducing the baking time? Only a second trial will answer these questions.

Back to blue smoke. I have a feeling that they put their mac & cheese under a broiler for 5 minutes to brown the bread crumbs (do they even have bread crumbs on their mac & cheese??)

Pan Fried Tofu with Spicy Scallion Garlic Sauce


 
Tofu is like a blank canvass. Literally BLANK. It is colorless and almost tasteless. Most people either "Like" or "don't like" tofu, and many people dislike it because of the soft texture. Tofu is rich in protein, calcium, and it can be tasty with little manipulation, such as this dish:

Pan Fried Tofu with Spicy Scallion Garlic Sauce.

Ingredients: (serves 4)
1 pack for medium/firm tofu (not soft tofu)

Sauce:
1 stalk of chopped scallion
1 clove of chopped garlic
hot pepper flakes/chilli powder
1 teaspoon sugar
2 tablespoon soy sauce
2 teaspoon sesame oil
2 tablespoon of cooking oil


Instructions:

1. Prepping the Tofu
Remove the tofu from the package and place it on a flat plate. Then put something heavy, like a pot filled with some water, on top of the tofu to apply pressure. The purpose of doing this is to squeeze most of the water out of the tofu. Remove the liquid that comes out from the tofu every 5 minutes until very few liquid is left.

2. Slice the tofu into bit size square pieces and pat the tofu dry.
3. Heat a non-stick pan with about 2 tablespoon of oil. Once the oil is hot, add the tofu and lower the heat to medium.
4. After 5-7 minutes, check the bottom of the tofu to make sure it looks golden brown. I tend to cook this a little longer so that the tofu will come out a little crunchy.
5. Turn the tofu around and cook for another 5-7 minutes.
6. Transfer the tofu on to a serving plate

7. Making the sauce
This is a technique that I like to use for making garlic/scallion sauce
a) Place the chopped scallion, chopped garlic, red pepper flakes/chilli powder in a small bowl
b) Heat some oil in a pot at low heat. Be careful as oil heats up fast
c) Once the oil starts to smoke a little, turn off the heat and pour the oil over the chopped scallion. Again, be careful when you do this. The ingredients will sizzle and it is quite harmless if you know what you are doing.
d) add the rest of the sauce ingredients and mix well

8. Spoon the sauce over the fried tofu and enjoy!

Ginseng Chicken Soup



My cousin showed up at my apartment one day holding a box of fresh ginseng and two Cornish hens and said "make this soup!"

I obliged and went online to find a recipe. I have been using this website as my go-to Korea recipe site http://www.maangchi.com/  since learning about it.  

Since ginseng is grown in Korea, this could explain why Ginseng Chicken Soup is commonly associated with Korea. However, I don't think this soup is native only to the Koreans. I was also told that Koreans consume Ginseng Chicken Soup only twice a year in the Fall when the weather turns cold.



                           Scallion, garlic, wolfberry and ginseng (forgot the jujube)


Ingredients: (serves 4)

1. One Cornish Hen (Cornish hen are young chickens and the meat are more tender than fully grown chicken)
2. 1/4 cup of rice
3. One dozen cloves of garlic (don't skim on this). Use it as whole garlic.
4. Green onions/scallions (roughly cut length wise, you don't want to chop this into pieces)
5. A few jujubes and a pinch of wolfberries (optional)
6. 2 small ginseng roots (fresh ginseng would be best but the dried kind is fine). Roughly cut into small pieces)
7. 1/2 cup of rice

Instructions

1. Wash and rinse the chicken.
2. Put the chicken in a pot and add just enough water to cover the chicken.
3. Add the rest of the ingredients including rice into the pot. Including the rice
(traditional way of cooking is to stuff the cavity of the chicken with the rest of the ingredients).
4. Cook the soup in medium heat for about 1.5 hours.
5. Season with salt and pepper




This soup taste refreshingly "sweet". Not sugar-sweet, but a 5th taste-sense kind of sweetness. It is hard to explain the taste. None of the flavor in this dish overpowers each other. What you get is a perfect blend of flavors with the unmistakeable smell of ginseng. True to its name, the meat of the Cornish hen is so tender that it falls apart and melts in my mouth.

It cost $15 to buy a bowl of this soup in K-town. How much would you like to pay me for a bowl of homemade soup?

Meringue Cookie


 
If you have been following this blog since the beginning, perhaps you remember my experience with making Meringue. My first attempt in making meringue failed because I was inexperienced. I have since learned a few things and I have been waiting for the right opportunity to redeem myself. I made Tiramisu cake recently and was left with extra egg whites, and thus an opportunity presented itself.


Ingredients:
3 egg whites
some sugar (this needs to be finely adjusted according to taste)

Instructions:

1. Preheat the oven to 200F. This is one important lesson that I learned from my mistake. You want to bake the meringue at low heat for an extended time.
2. Beat the egg whites with a handheld mixer in a metal bowl. This is something they never emphasize in a recipe book. Never ever beat egg whites in a plastic bowl. There is a reason behind this and it involves some chemistry knowledge. It is too long for me to describe it but if you are curious, simply do some web search.

3. Keep checking the beat egg white until stiff peaks starting to form. Sorry, I don't have the space to describe what a stiff peak is. You can do some homework here.

4. Once stiff peaks are forming, add a couple tablespoon of sugar to the beat egg white and give it an additional mix for a few seconds. The amount of sugar can be adjusted based on your preference.

5. Lay down a piece of parchment paper (ESSENTIAL) on a baking sheet and scoop the meringue on to the baking sheet.

(if you want perfectly shaped meringue, then you will need a pipping bag, the kind people use to apply frosting/icing/whipped cream on top a cake)

6. Bake the meringue for 1 hour. You can take one out to test the doneness.





I only had meringue cookie twice and both times were cookies made by myself so I have no idea how should meringue cookies taste or feel like. This meringue cookie breaks apart easily and tasted like cotton candy. I think I might have used too much sugar because the sugar melts in my mouth and sticks between the teeth.

Second time is a SUCCESS!!

Rice Milk/Horchata



 
My aunt used to make Rice Milk whenever she visited us and that was my first time trying rice milk. Before that, I have never associated rice as a beverage since it was more common to have soy milk and cow milk.

Then a few years ago, my friend introduced me to a neighborhood Mexican restaurant and we ordered rice milk, also known as horcharta. I fell in love with this drink and since then, I have always ordered horcharta at every Mexican restaurant that I ate at.

I always find the restaurant Horcharta over-sweetened and either too thick or too thin. Also, many horchatas that I tried were made from instant rice powder that tasted artificial. Therefore, I have decided to make my own rice milk as inspired by my aunt.

The first time I tried making rice milk turned into a disaster and I learned a few tips which I would like to share with you.

Ingredients
(serving: 4 glasses of rice milk, could be more or less depending on your preferred consistency)

1 cup of rice

(many recipes suggest long grain rice, some use Basmati rice. I used medium grain Botan rice, just because this is the rice that I eat. My point is, if you already have rice at home that you use, there is no need to find the exact kind of rice. I think any rice will work unless you are a purist/traditionalist).

Sugar
Cinnamon power
vanilla extract

Equipments
Blender
Sieve/Cheese Clothe

 
                         Thanks CL for the gift of this blender

Instructions
1. Mix 1 cup of rice with 4 cups of water.
2. Blend the mixture at high speed until most of the rice particles are broken down into tiny bits.
3. Let this mixture sit at room temperature for 30-60 minutes.


 
                                                          Unfiltered rice milk


4. Filter the rice milk through the sieve/cheese clothe or in my case, an oil screen http://foodmolecule.blogspot.com/2011/09/salmon.html
5. Heat the rice milk under low heat for about 10 minutes, stir occassionally
(At this point, you will see some gooey cooked rice forming)
7. Turn off the heat, filter the rice milk one more time.


This is essentially the finish product. What's left is adjusting the consistency of the rice milk to your preferred consistency. If you want a thick rice milk, return the rice milk to the heat and keep simmering but if you want thin consistency, simply add more water. Next, add sugar to sweeten the rice milk. You can consume this rice milk when it is hot/warm/cold. Again, entire up to you. Also, a sprinkle of cinnamon and a splash of vanilla extract right before consumption rounds out this drink. 


How is my Horchata compare to restaurant-version? First thing that I noticed is that my homemade rice milk is rice color, which is translucent white. It is not "creamy/pearly white" like the ones in the restaurant, which is a sign of artificial coloring. Second, the rice flavor does shine in my homemade rice milk unlike the restaurants' which are over-sweetened or tasted artificial.

One last thing, I am surprised how little rice milk a cup of rice grain yields, which is not a lot. If you want one week worth of rice milk for a party or for yourself, you might need at least 5-6 cups of rice.

Tiramisu Cake

This dessert needs no introduction, it is one of my favorite desserts. As it turns out, it is a very simple dessert to make. 

The recipe that I used is by Giada, which is very standard compare to all other tiramisu recipes. As usual, I made some slight modifications. Here is Giada's recipe http://www.foodnetwork.com/recipes/giada-de-laurentiis/tiramisu-recipe/index.html


Ingredients (serves 4; everything in here is half of the original recipe)
 
3 egg yolks
1.5 tablespoon sugar
0.5lb of mascarpone cheese
1/2 cup of expresso, cooled before used
12 ladyfingers (in my case, I couldn't find ladyfingers, so I used loaf cake, which I thinly sliced)
A piece of dark chocolate (any chocolate from the candy section is fine)
Rum/amaretto (I did not use this because I don't have any)

Instructions

1. In a large bowl, beat the egg yolks and sugar until the mixture turns thick and pale. (Yes, the yolk mixture will turn white)
2. Add the mascarpone cheese and continue beating the mixture until smooth.
3. Add 1 tablespoon of expresso and mix thoroughly.

Arranging the tiramisu cake

1. This is where I use a technique which defers from others. In most recipe, you soak the ladyfingers in the coffee. However, this will cause the ladyfingers to break apart very easily. Instead, I use a spoon to drizzle the coffee over the ladyfingers after I lay them down.

2. Place a layer of ladyfingers at the bottom of a pan/large bowl. Add a scoop of the egg/cheese mixture over the ladyfingers.

3. Sprinkle some shaved chocolate.

4. Repeat step 2 and 3.



How did I do with my first (surely will not be my last) try? My food tasters used the following words to do describe it "light", "not too sweet", "just the right cheese and cake ratio"(this can be attributed to the way I plated my tiramisu cake as I added lots of cheese mixture on top of thinly sliced caked).

I am not afraid to say that this was a successful try. Delicious is an overused word in describing food but there is not better word. DELICIOUS!!



Footnote:
According to my Italian friend, traditional tiramisu cake is served in a bowl, not a plate and it shouldn't be served like a conventional cakes, which are sliced.
