The edible portion and the most nutrient-rich part of some vegetables grows underground in a bulbous shape. This shape is comprised of many fleshy layers that overlap and act as a sponge to bring nutrients into the plant. Onions, which are bulbs, have excellent keeping abilities and will not deteriorate–even lasting throughout the winter months.
The bulb is a flavorful and versatile vegetable that is an important aromatic element in the culinary world. An excellent addition to most preparations because of their perfume and texture, they enhance any dish in which they are used. Because there are so many varieties of bulbs to choose from, the flavor combinations are endless. Onions, leeks, garlic, and shallots all belong to the bulb family and are thought to have originated from Central Asia. We discuss each of these types of bulbs next.
