Chicken Marinade
Flour Dredge
General Tso’s Sauce
The Rest
Prep chicken. Jaccard each breast ~10 times per side (or poke 20–30 times per side with a sharp fork). Slice each breast into 3–4 long strips, then cut into ~¾in cubes.
Marinate. In a medium bowl combine soy sauce, mirin, MSG, baking soda, and potato starch. Add chicken and mix to coat. Rest 20 min.
Make dry mix. In a large bowl whisk flour, baking powder, garlic powder, salt, and potato starch until uniform.
Build adhesion batter. In a separate bowl, weigh 250g of the dry mix. Add 300g water and stir until it looks like thin pancake batter/low-quality paint.
Make craggy bits. Pour 200g of the batter into the remaining dry mix. Briefly whisk, then use your hand to rub and crumble until you've got rice-to-lentil sized pebbles with a powdery background.
Dredge. Toss about ⅓ of the marinated chicken in the batter bowl to lightly coat (be gentle to keep marinade on the meat). Lift, let excess drip, then drop into the craggy dry mix. Fluff/tumble to build a strong base layer without rubbing it off. For each piece, shower on extra craggy bits and give a soft squeeze, then shake off excess. Repeat with remaining chicken.
Rest. Spread breaded chicken on a ¼ sheet tray and refrigerate 20 min.
Sauce. In a bowl whisk soy sauce, sesame oil, mirin, rice vinegar, sambal, ketchup, sugar, brown sugar (in the 70g sugar), cornstarch, and MSG until smooth. Set aside.
Fry. Heat neutral oil in a Dutch oven to about 325°F (1.5–2in depth; never fill pot more than 50%). Fry chicken in two batches. Gently lower in, don't touch for 1 minute, then nudge to prevent sticking. Fry 6–7 min until deeply golden "McNuggery." Drain on a rack or paper towel. Repeat with second batch.
Stir-fry aromatics. Carefully move the hot oil aside (off oven). Heat a wok or large nonstick pan over high. Add a squeeze of oil, then scallions; stir-fry 60 sec. Add cracked chiles (optional) and toast briefly. Add ginger and garlic; stir constantly 30–40 sec until just fragrant.
Glaze. Pour in the sauce around the hot pan edge. Bring to a boil and reduce 15–20% until it leaves a trail. Add fried chicken and toss ~30 sec to simmer in the sauce.
Serve. Pile over steamed rice. Spoon on any extra sauce from the wok. Garnish with reserved scallion greens.
