Any chef will tell you, if they don’t have onions on hand, they pretty much can’t cook anything. While we do know that is an exaggeration, onions are a kitchen essential. They are used as a base for everything; soups, stocks, saut_s or just caramelized and added to dishes. Onions can be used raw, or they can be cooked, allowing their flavors to mellow. White onions are typically stronger that yellow or red onions. Onions (dry) are typically divided into two categories: Storage _ Generally available August _ March. Characterized by multiple layers of thick, dark skin, intense flavor, and higher percentage of solids. Storage onions may be red, white, or yellow in color. Spring/Summer _ Generally available April _ August. Characterized by thin, light-colored skin and a sweet, mild flavor due to a higher water and sugar content. Because of their thin skins, spring/summer onions are more susceptible to bruising. Spring/summer onions may be red, white, or yellow in color.
