Why does my stir-fry beef always turn out tough and chewy?
I've been trying to make those tender, juicy beef stir-fries like your average takeout place does, but mine always comes out tough no matter what I try. I've used flank steak, sliced it thin against the grain, and cooked it hot and fast. Still chewy. Am I missing a step like velveting or baking soda? Is my pan not hot enough or am I overcrowding it?
What's the actual trick here that restaurants use but most recipes leave out? I don't want to keep wasting good beef on disappointing dinners.
