Choose the closest swap based on what you have: soy+brown sugar, mirin+honey, tamari+maple, hoisin+soy, or a ready-made stir-fry glaze.
Swap 1:1 for most bottled options; for thicker/smokier substitutes, start at ¾ and add more as needed.
Simmer 30–60 seconds if your base is runny so the sugar dissolves and the sauce clings like teriyaki.
Match the glaze level: thin with water for stir-fries or thicken with a tiny cornstarch slurry if it won’t coat.
Final adjust: add a pinch of sugar for sharper saltiness, or add a splash of soy/rice vinegar to brighten and balance.
