Tomato and Onion Confit
Unlike most other vegetables, tomatoes release a lot of moisture as they cook, so there’s no need to completely submerge them in the oil (or added liquid). It is this “cooking in its own juices” that makes this dish a “confit” (see page 232). Because this technique cooks out most of the moisture from the vegetables, it concentrates the sugars, for a sweet, jamlike condiment to serve with roasted, grilled, or sautéed meats (such as the calf’s liver on page 253). While the confit cooks, stir very gently, or the tomatoes and onions may fall apart.
