I used to work at a Chinese restaurant as a delivery driver. My boss made the best kung pao chicken that I’ve ever had in my life (better than Kenji Lopez-Alt’s recipe, which I’ve made several times). He would never give me the recipe. Like, dude, really? I’m not gonna open up a Chinese restaurant! I’ve spent a long time trying to duplicate it. If I ever do crack the code, I’ll post the recipe.
