Onion
Onion is a vegetable used worldwide for cooking. It is actually one of the most used ingredients in many cuisines, including Indian, Chinese, Mexican, Spanish, Italian and Greek. Onions have a distinctive strong flavour and a pungent odour and come in a wide variety of forms and colors. You can get white, yellow or red onions, ranging from small (about 15mm in diameter) to large (up to 100mm in diameter or more). They generally have an outer skin (called paper) covering the core that is made up of layers.
