What are common mistakes when making Gan Bian (干煸) — Sichuan Dry-Frying: Green Beans and Beef?

Question

Accepted Answer

Too much oil: Even a small excess of oil turns the dish into a regular stir-fry — the gan bian technique requires almost no oil after the initial coat. Too-high heat: High heat scorches the surface before the interior moisture is removed. The gan bian process is medium, sustained heat.
