O is for Onion

Onions are round and covered with yellow, white or red papery skins. First they must be peeled and then can be sliced, diced, chopped, or grated. They can be eaten raw, cooked, boiled, or pickled. They are best known for making you cry. This is because of a unique chemical reaction. Did you know that chilling the onion or cutting it under cold water might help keep you from crying?
