Onion

Onion is sharp and sulphurous raw, then soft and sweet once it has had time in the pan. It starts beef stew, shakshuka and the sausage and chickpea stew, and gets stir-fried with pork chops. Cook it slowly over medium heat until translucent before adding anything else, because rushing it leaves a harsh, raw edge.
