Not a common allergen

Flavor guide

Raw onions are pungent, sharp, and sulfurous, with a crisp bite that is completely inappropriate for babies and too intense for most adults to eat in volume. Long, slow cooking transforms them: sauteed for 15 minutes they become soft and mellow, caramelized for 40 minutes they turn deeply sweet and almost jammy with a rich savory depth. They pair naturally with butter, potato, lentils, tomato, thyme, aged cheese, and egg.
