Onions are layered bulbs from the allium family, known for their sharp, savory bite when raw and their sweetness as they cook. They begin crisp and firm, then soften and can turn golden and mellow when sautéed or caramelized. Across many Eastern cuisines, onions are used as a base for curries, stir-fries, soups, and braised dishes, adding depth and aroma. Cultivated for thousands of years, they have long been valued in cooking across Asia and the Middle East.
