French the drummettes — cut a ring around the thin end of the bone, push the meat down with a paper-towel grip to form a lollipop, wrap the bone tip in foil.
Marinate — rub ginger garlic paste, soy sauce, chili, pepper, salt, vinegar into the meat; rest 30 min (up to 4h refrigerated).
Make the batter (cornflour, flour, spices, cold water to paint-like consistency) and heat oil to 350°F/175°C.
Fry in batches 8–10 min until deep golden, internal 165°F/74°C; drain on a wire rack.
Toss in schezwan glaze — sizzle garlic and spring onion whites, add schezwan sauce, ketchup, soy, sugar, vinegar, water; toss lollipops 1–2 min.
Serve hot with spring onion greens and sesame seeds.
