This sweet-savory combination was the star of my takeout order! Tender chicken glazed with tangy teriyaki and juicy pineapple chunks that balance perfectly.
Cut the chicken thighs into bite-sized pieces. In a large bowl, toss chicken with 1 beaten egg and 1/3 cup cornstarch until evenly coated. Let sit 10 minutes while you heat oil.
Heat 1.5 cups neutral oil in a wok or deep skillet over medium-high heat (350°F). Fry chicken pieces in batches without crowding, 4–5 minutes total, turning until golden and crispy. Remove and drain well.
Carefully pour off excess oil, leaving 1 tablespoon in the wok. Add garlic and ginger; sauté 30 seconds until fragrant.
Stir in soy sauce, brown sugar, honey, rice vinegar, water, and sesame oil. Bring to a simmer and cook 1–2 minutes until sugar dissolves. Add pineapple chunks and simmer 2 more minutes.
Mix 1 tablespoon cornstarch with 2 tablespoons water, then slowly stir the slurry into the wok. Cook, stirring, until the sauce thickens and becomes glossy.
Return fried chicken to the wok. Toss rapidly over high heat for 1 minute, coating chicken completely in sauce (the 'Panda technique' for sauce adherence and wok hei).
Sprinkle in sliced scallions, give a final toss, and serve hot with steamed rice if desired.
