Ingredients

Marinade
1 tablespoon soy sauce
1 tablespoon shaoxing rice wine or 1 tablespoon dry sherry
2 large egg whites
Sauce
1/4 cup chicken broth
1 1/2 tablespoons tomato paste
1 tablespoon soy sauce
1 tablespoon rice vinegar
1 teaspoon hoisin sauce
1 teaspoon chili sauce
1 teaspoon sesame oil
1 tablespoon sugar
1 teaspoon cornstarch
Chicken
1 lb boneless skinless chicken thighs, cut into 1 inch cubes
1 teaspoon white sesame seeds
1 1/2 cups cornstarch
1/2 teaspoon salt
1/2 teaspoon fresh ground black pepper
3 cups vegetable oil or 3 cups peanut oil
1 tablespoon vegetable oil or 1 tablespoon peanut oil
8 dried whole red chilies or 1 teaspoon crushed red pepper flakes
2 garlic cloves, minced
2 scallions, thinly sliced (green parts only)

Preparation

It is recommended that you use an instant read digital thermometer to maintain correct oil temperature while frying.
In a large bowl, combine the marinade ingredients and add the chicken. Stir gently to coat the chicken and allow to stand at room temperature for 15 minutes.
In a small dry frying pan, toast the sesame seeds until they are light brown in color and aromatic. Transfer to a small dish and set aside.
In a small bowl, combine the sauce ingredients and stir until the sugar and the cornstarch are fully dissolved. Set aside.
Toss the 1 1/2 cups cornstarch with the salt and pepper in a large bowl or deep plate. Coat the marinated chicken in the cornstarch mixture and shake off any excess before frying.
Heat the oil in a wok or heavy-bottomed pot until it registers 350 degrees F. Working in 2 or 3 batches, add the first batch of chicken cubes and deep fry until lightly golden on the outside and cooked through (3-4 minutes). Remove the chicken with a slotted spoon and drain on a plate lined with paper towels. Repeat with the rest of the chicken.
When finished cooking chicken, take the first batch and return then to the 350 degree oil. Continue cooking for 30-45 more seconds so they become golden brown. Repeat with the rest of the chicken.
Transfer the oil to a heat-proof container. It will take about 1 hour to fully cool, after which you can transfer it to a container with a tight lid for disposal. If you used a wok, just wipe down the inside with a paper towel and if you used a heavy-bottomed pot, switch to a large skillet for stir-frying.
Heat the wok or skillet over medium-high heat until a bead of water sizzles and evaporates on contact. Add the 1 tbsp of oil and swirl to coat the wok or pan. Add the chiles and garlic and stir-fry until just fragrant (20 seconds). Pour in the sauce mixture and heat briefly to thicken (just under a rolling boil).
Return the chicken to the wok and stir well to coat with sauce. transfer the chicken to a serving dish and garnish with sesame seeds and scallions.
