1. Marinate the chicken 

Marination is a common technique to infuse flavor to meat in most Asian cooking. 

The marinate for the Korean fried chicken consists of some fundamental ingredients since the most significant part of the flavor is contributed from the sauce glazing the meat. 

The best parts of the chicken are thighs and wings, although any part is suitable. 

  • Clean the chicken thighs and wings and drain in a colander.
  • Dab dry with a paper towel or wipe with a dry cloth. The goal is to keep it dry so that the chicken will be crispy after deep frying. 
  • Marinate with salt, ground black pepper, and ginger juice for at least one to two hours. 

The actual duration of marinating the meat depends on the chicken’s size. Also, it is better to marinate overnight when time is not the issue. You can also pre-marinate and freeze the chicken, which can be kept for several weeks in the freezer. 

2. How to fry the crispy chicken 

After the chicken pieces are well marinated, remove them from the refrigerator or freezer and wait until it is back to room temperature. If you deep-fry the chicken while it is still cold, the chicken’s inner part may not cook through.

Coat the chicken with potato starch 

  • Place some potato starch (or cornstarch) in a mixing bowl (80g should be sufficient for 1.2kg of bone-in chicken). 
  • Add a teaspoon of baking powder and mix well. 
  • Coat the chicken thoroughly with the starch.
  • Remove the chicken to let it rest for five minutes. Then deep it into the starch once more to ensure the surface is entirely covered. This step is to make sure the chicken’s surface is fully protected from the direct heat from the oil. Any exposed part will potentially be overcooked and becomes dry after deep-frying. 

Double frying the chicken  

There is more about double frying in the next section. Meanwhile, here are the detailed steps. 

  • Heat adequate oil to 160°C/320°F. 
  • Shake off any excess starch, place the chicken in the oil to deep-fry for six minutes for the wings, and ten minutes for the drumsticks. 
  • Do not crowd the chicken pieces in the oil because they will stick together. The coating will break when you pull them apart.
  • Remove the chicken after the first round of deep-frying. Let it cool for five minutes. 
  • Bring the temperature of the oil to 190°C/375°F. Return the chicken to the oil to deep-fry once more until golden. 
  • Drain the chicken on the rack, and then clean up the excess oil with a paper towel.

3. Make the sweet and spicy sauce 

The uniqueness of Korean fried chicken comes from the sauce. 

You may not taste anything quite like this unless you are a fan of Korean food. This unique taste comes from the Korean chili paste called Gochujang. 

Gochujang is the main component of the sauce, and you should include a generous amount. I also add some dry chili to add some extra capsaicin punch to it.

But it is more than just a hot sauce. There is also ketchup, honey, sugar, soy sauce, vinegar, sesame oil, and sesame seeds 

These ingredients are amalgamated into a complex flavor that can be found only in Korean cuisine. 

The honey and sugar thicken the sauce, making it ideal for glazing the chicken’s surface to form a glossy finish. 

Here are the steps 

  • Cut the dry chili into short sections, then remove as many seeds as possible. (Keep the seeds if you like it to be hot and spicy).
  • Heat the vegetable oil in a pan, add the dry chili, minced garlic, and ginger. Saute until aromatic. 
  • Add the ketchup, Gochujang, brown sugar, soy sauce, and vinegar and heat it until it starts to bubble. 
  • Add some water if it is too thick.
  • Remove from heat. Stir in the honey and sesame oil and toasted sesame seeds. 

4. Glaze the chicken with the sauce 

  • Dip each piece of chicken into the sauce to coat it thoroughly. Don’t worry. The crust will remain crunchy with the double frying method.
  • Arrange the chicken on a serving plate. 
  • Drizzle the remaining sauce on the chicken. 
  • Garnish with more toasted sesame seeds and scallion.

What is Gochujang (Korean chili paste)? 

Gochujang (고추장; 苦椒醬; gochu-jang) is an integral ingredient in Korean cooking with a savory, sweet and spicy taste.  It is a chili paste made of chili powder, glutinous rice, and fermented soybean powder.  The flavor is different from any other chili sauce or chili paste, and there is no exact substitute.  Sriracha may be close to it, but it will still taste different. Fortunately, it is now available at most of the Korean Grocery stores and online.

If Gochujang is unavailable, you can use some miso to make it at home since miso is also made with fermented soybean.

Here is the instruction to prepare a homemade version of Gochujang.

  • Dissolve 1.25 cups of brown sugar in 1 cup of boiling water.  
  • After that, add 1/2 cup of chili powder and mix well. 
  • Next, add 1 cup miso over low heat until the mixture starts to thicken. 
  • Switch off the stove to let it cool for a minute, add 1 tbsp salt, 1 tsp sake, and 1 tsp rice vinegar. 
  • Let it cool thoroughly and store in the refrigerator.

Dakgangjeong is the chicken version of the Korean confectionery called Gangjeong. Gangjeong is made by heating the rice syrup and mix with puffed rice, sesame seeds, or nut, then place in the refrigerator until it solidifies.  The sauce for dakgangjeong share has similarity to the confectionery, and sometimes it is called candy chicken.

More tips to make the best Korean fried chicken

1. Choice of the chicken parts 

Which is the best part of the chicken for Korean fried chicken? Drumsticks and wings are my choices, and a mix of both is even better for presentation. 

Chicken breast is the next in line. Since the meat is relatively thicker and tougher than wings, it is recommended to marinate longer or even overnight. Make sure the breast meat is covered with the potato starch coating thoroughly to prevent it from drying out during deep-frying. 

2. Potato starch vs. cornstarch vs. flour 

While most Korean fried chicken recipes call for potato starch, it may not be readily available at certain places. 

In this case, you can substitute it with cornstarch (sometimes labeled as cornflour) on one to one basis. The result by using either one is identical.

Regular flour is not suitable as it will not yield a crunchy coating.

3. Baking powder 

The baking powder creates a crunchy crust by increasing the coating’s surface area while releasing gas in hot oil. The air bubbles break up the thick coating, resulting in a light and crispy fried chicken. 

A small number of people may be sensitive to it and claim that it has a bitter taste and feels dry on the tongue. Therefore I only add not more than half a teaspoon per 100g of potato starch. 

3. Duration of deep-frying the fried chicken

The duration of deep-frying in the recipe only serves as a guide. The actual time depends on the size and the parts of the chicken. 

For your reference, I fried the drumsticks for ten minutes at the lower temperature, followed by four minutes at the high temperature. As for the wings, it is 5 minutes, followed by another 3 minutes. 

4. The science behind the double frying method 

Why is the double-frying method works? 

I have read different theories and summarize it as below. 

  • When you dip the chicken into the oil, the water close to the chicken’s surface starts boiling. Henc, the surface starts to get dryer, forming the crust. 
  • When the chicken is cool after the first deep fry, the moisture at the inner part of the chicken migrates to the surface, making the surface soggy again. The second fry will boil off this moisture, transforming the surface to an extremely crispy crust. 

Therefore, the chicken must be cool for a few minutes to let the internal moisture drift to the surface before executing the second fry. 

This double-frying method can crisp up other foods, like making potato chips that crisp outside and moist inside.

In step 3 do you mean coat in "d" or is it supposed to be "b". I have used recipe swapping d for b in step 3 and turned out perfect. Great recipe, just an editing mistake i assume.
