I stepped up on a cinder block to enter the open kitchen and realized then just how short the cook was; he flicked on the burner and the flame shot up as high as his chin. His broom closet-size kitchen swelled with heat and even with my average height, I towered over him awkwardly as he wielded the wok with beef and soy sauce. "You must play basketball!" he suggested.
On his kitchen wall and out of reach of the blazing flame, plastic bags of spices hung from low-set rusty hooks, and his windowsill nearby lay scattered with tangerine peels set out to dry in the sun. Cooks in China are in the habit of keeping the peels of the tangerines they eat and spreading them out to dry in the sun for later use. Then they just rehydrate a few pieces whenever they want to add a nutty, slightly bitter note to a stir-fry or stew. Tangerine Beef is a Sichuan specialty and tall on flavor.
