Instructions
Combine all the marinade ingredients in a bowl and mix well. Add the chicken cubes, toss to combine, and marinate for 20 minutes.
Whisk together all sauce ingredients in a separate bowl.
Heat vegetable oil in a wok over high heat until shimmering around 375 degrees F. Put the tapioca flour in a large bowl, add marinated chicken, and toss to coat. Be sure to coat each piece generously.
Fry the chicken in the hot oil in two batches until they are golden brown, about 4 minutes. Drain on paper towels.
Remove all about 2 tablespoons of the oil from the wok. Add garlic and ginger to the wok and stir-fry for about 30 seconds, until fragrant. Add chiles and stir-fry for another 30 seconds.
Whisk the sauce mixture to recombine and add to the wok. Cook until the sauce thickens, about 1 minute.
Transfer chicken to the wok and toss to coat. Stir in sesame oil. Garnish with sesame seeds and scallions.
