In a bowl, whisk together the egg white, 2 Tbsp cornstarch, 2 Tbsp wine, and 2 Tbsp soy sauce. Add chicken and toss to coat. Cover and marinate in the refrigerator for up to 2 hours.

Sauce - In another bowl, whisk the remaining cornstarch and 1 Tbsp chicken stock until smooth. Add the remaining chicken stock, soy sauce, vinegar and sugar. Whisk to combine. Set aside until ready to finish the dish.

In a large wok or pot, heat enough oil to come 3 inches up the side to 350°F.

Remove the chicken from the marinade and carefully slide into the hot oil. Fry, turning until golden brown and cooked through, about 2 minutes. Remove and drain on paper towels.

Discard all but 1 Tbsp of the oil from the wok. (Alternatively in a clean wok or saute pan, heat 1 Tbsp of oil over medium-high heat.) Add the chili peppers and stir-fry until nearly black. Add garlic, ginger, red pepper flakes and 1/2 cup green onions. Stir-fry until fragrant, about 15 seconds. Add the chicken stock sauce, bring to a boil and cook, stirring, until the sauce thickens, about 1 minute. Remove from the heat.

Arrange the chicken on a platter and pour the sauce over it. Garnish with cashews and green onions. Serve with hot rice.
