Pickled red onions offer a bright, punchy flavor profile that balances sharp acidity with a mild, sweet onion undertone and a crisp-tender crunch. The harsh raw bite mellows into a vibrant, refreshing tang as they cure. Core Taste and Texture Brightness & Acidity: A sharp, clean tang hits first from the vinegar brine. Sweetness: A subtle, natural sugar-kissed finish cuts through the sour bite. Aromatics: Faint earthy and peppery background notes come from the raw allium layer. Crunch: Firm yet tender bite that retains a refreshing snap.
