Spicy Korean Fried Chicken Sandwich

Yangnyeom Korean Fried Chicken Sandwich

I was inspired by my addiction to Korean fried chicken and chicken sandwiches and thought what if I mix these two together? Especially if the crispy fried chicken were coated in yangnyeom sauce, I would order this every time I go to any Korean fried chicken joint! That sweet and spicy sauce is my favorite and chicken sandwichs make the most of that flavor with spicy mayo and radish in between two toasted brioche buns.

The Marinade

The marinade mix contains cajun seasoning, pickle juice, black pepper, salt, gochugaru, gochujang paste, and buttermilk.

The part of the chicken for this recipe will be the thigh. Although it is not as thick and big as the breast, but it is much more tender which is perfect to bite into a sandwich. When you get chicken thighs at the supermarket, make sure to get the ones that already boneless and skinless. This will drastically make this easier for you. When preparing the chicken, feel free to remove any fat that is left over. This is completely up to your preference. After you have prepared the marinade, let it marinate for at least an hour or so. The long the better, the chicken will be when it is fried.

The Dry Batter Mix

In this recipe, the choice of batter will be centered around potato starch. Potato starch has a higher frying temperature so it does not burn too quickly in comparison to other types of starches. This will allow you double fry without having to worry about browning the chicken too much. However, potato starch is pretty difficult to find if there are no Asian supermarkets near you, so cornstarch is the next best option. When you are using cornstarch,  add flour to the batter. That will be 1/2 cup of flour and 1 1/2 cup of cornstarch.

Yangnyeom Sauce

Yangnyeom sauce is a sweet and spicy sauce that is made from gochujang and syrup, but this recipe will replace the syrup with honey. With the balance of sweet and spicy, this will give your chicken that much needed flavor that will make you want to savor every single bite. When you are cooking the sauce on the pan, there is no particular order for the sauce, but if you want it to be a bit watery, add more water.
