This chicken karaage don is inspired by one of my favorite Japanese grocery stores. I think it's overall very easy to make, but of course you need to deep-fry the chicken which I know many of you dislike doing. Anyways, this dish is totally worth it and super satisfying.
To a medium bowl, add the chicken thighs, garlic, ginger, soy sauce, sake, sugar, salt, and egg white. Mix well then marinate for at least 40 minutes.
In another medium bowl, whisk together the cornstarch and tapioca starch. Add 2 tablespoons of this mixture to the marinade (this helps thicken the marinade so that the skin will be thicker).
Working one piece at a time, coat each piece of chicken in the starch mixture then transfer to a baking sheet. Make sure to shake off excess starch otherwise there will be white specks over the crust after frying.
Let the chicken rest for 15 minutes to allow the starches to hydrate.
Heat about 1 inch of oil to 350°F in a Dutch oven. Use a spatula to release the chicken from the baking sheet. Deep-fry the chicken in two batches for 4-5 minutes until golden brown and crispy. Transfer to a wire rack to drain excess oil. Allow the temperature to come back to 350°F before starting the next batch.
For the spicy sauce
Simply combine all the ingredients in a small bowl.
For the boiled lettuce
To a medium pot, add the salt, oil, and about 8 cups of water. Bring to a boil.
Use your hands to tear the lettuce into bite-sized pieces. I usually make them about 3 inches wide.
Dunk the lettuce in the boiling water for 10 seconds then drain and set aside on a plate.
To assemble
Scoop 2 cups of rice into a bowl. Add a layer of lettuce followed by a generous drizzle of spicy sauce. Finally, add the chicken on top. I also recommend serving this with lemon wedges for people who like it more sour. Enjoy!
