In a bowl, combine the ingredients for the bang bang sauce and set aside.
Cook the pasta in salted boiling water until al dente; drain and set aside.
Meanwhile, prepare the batter by mixing flour, corn starch, milk, salt, and black pepper. Start with ¼ cup of milk then add 1 tablespoon of milk at a time, as needed, to achieve a consistency similar to pancake batter.
Add the chicken and mix to coat.
In another bowl, add panko bread crumbs. Let excess batter drip off from the chicken, then coat it in the panko bread crumbs, gently pressing the bread crumbs into the chicken. Place the coated chicken onto a baking sheet.
In a skillet, heat ½ inch of oil to 375°F and fry the chicken for 5-8 minutes, flipping halfway, until cooked through and golden brown. Drain on a wire rack.
In a mixing bowl, toss the pasta with the chicken and bang bang sauce. Garnish with scallions and sesame seeds if desired and serve immediately.
Notes
Fry in batches as needed. Overcrowding the pan will decrease the temperature of the oil.
Adjust the hot sauce to your taste. Add more if you like it spicy!
If the batter is too thick, add 1 tablespoon of milk at a time as needed, to achieve a consistency similar to pancake batter. If the batter is too thin, add 1 tablespoon of flour at a time as needed.
Nutrition estimate does not include oil absorbed during frying.
