Mongolian Beef

Method

1. season8 min
   slices dusted in cornstarch, rested 10
   the beef tossed through the cornstarch until every slice wears a dry white coat, rested while the oil heats — the rest hydrates the dust into a jacket that fries crisp instead of shedding; this dish is the cornstarch-crust thesis at its most extreme
2. fry8 min
   375°F shallow oil, batches, 2 minutes to crisp edges
   the slices in a single layer per batch until the edges crisp and brown — drained on a rack; they will look overdone and be exactly right, because the sauce ahead is a softening force
3. simmer3 min
   sauce: aromatics bloomed, then soy + sugar + water
   all but a spoonful of oil poured off, garlic + ginger + flakes bloomed thirty seconds, then soy + brown sugar + water at a hard simmer until it thickens to syrup — this sauce needs no cornstarch; the sugar concentration IS the thickener, which is why it candies the way it does
4. glaze2 min
   beef + scallions tossed through the syrup
   the crisp beef back in with the scallion lengths, tossed until lacquered — the scallions barely wilt, staying half-raw and sharp against the sweet dark beef, which is the entire balance of the dish; over rice immediately, while crust and candy coexist
