onion; sliced or chopped

About
The onion (Allium cepa) is a bulbous, biennial flowering plant of the amaryllis family, native to Central Asia and now cultivated worldwide. The edible bulb consists of concentric layers of fleshy leaves covered in papery skin, typically white, yellow, or red depending on variety. Raw onions possess a pungent, sulfurous flavor that becomes sweet and mellow when cooked through caramelization of naturally occurring sugars. Major varieties include yellow (strong flavor, stores well), white (milder, used fresh and in cooking), and red (sweet, purple-hued, good raw). The flavor intensity depends on maturity, variety, and cooking method.
Culinary Uses
Onions are fundamental aromatics in countless culinary traditions worldwide. When sliced or chopped, they form the flavor base for soups, stews, sauces, and braises across European, Asian, Middle Eastern, and Latin American cuisines. Raw sliced onions appear in salads, salsas, and as condiments; cooked versions develop sweetness through caramelization and are essential to French onion soup, Spanish sofrito, Italian soffritto, and Asian stir-fries. Chopped onions are the starting point for stocks, mirepoix, and aromatic foundations. Their versatility stems from ability to marry with virtually all savory ingredients while providing layered flavor development.
