These round, flat Italian onions are about one to two inches in diameter. They’re available in the fall. Pronounced chip-oh-LEE-nee this is a smaller, flat, pale onion. The flesh is a slight yellowish color and the skins are thin and papery. The color of the skin ranges from pale yellow to the light brown color of Spanish onions. These are sweeter onions, having more residual sugar than garden-variety white or yellow onions, but not as much as shallots. The flavor is sweet and rather mild. Also available is a red cipollini.
