Flavor profile

Sweet onions (Vidalia from Georgia, Walla Walla from Washington, Maui from Hawaii, and others) are not a different species from standard onions — they are Allium cepa cultivars grown in specific soil and climate conditions. The low-sulfur soil of regions like Vidalia, Georgia means the plants absorb less sulfur, producing less of the pungent sulfur compounds and more of the natural sugars (10–12% sugar content versus 5–7% in pungent onions). The result is an onion that is genuinely pleasant to eat raw — in salads, on sandwiches, and as onion rings where the mild sweetness is an asset. Cooked, sweet onions lose their advantage: the sulfur compounds in all onions convert to sweetness during long cooking, so standard storage onions and sweet onions produce similar results in caramelized onion applications. Use sweet onions where raw or lightly cooked onion is a feature (Southern-style sweet onion slaw, Vidalia onion pie, onion rings, Georgia sweet onion sandwiches); use storage onions (more complex flavor potential) for long-cooked applications.
