Most grocery stores offer white and yellow onions. Texans cook with lots of yellow onions, which are sometimes called sweet onions because of their sweeter flavor. Other vegetables in the onion family include garlic, and leeks. Garlic is extremely potent and flavorful. Leeks consist of long green stalks with white bulbs on one end.
Leeks have a milder flavor then onions, and are wonderful in soups.
Health Properties Onions contain juices that act as a natural antibiotic. They contain mustard oils which stimulate the appetite. Consequently, they are good to eat when suffering from a cold or some other kind of virus. Garlic contains all these properties in a compact, strong form. Some people treat their colds and flus with a tall grass of carrot juice with one or two cloves of garlic.
