Rakkyo Onion
Latin Name: Allium chinense

Rakkyo onions are like a cross between chives and grey shallots. Their greens can be used just like chives for garnish, and their bulbs have a strong pungent flavor and are often pickled whole. They grow like chives, produce a looser flower than the usual tight onion blossom pompom, and are grown throughout Asia, the bulbs a staple in most kitchens.
Rakkyo onion is a common name that often refers to this specific variety Allium chinense, but is also often used as a general term to refer to scallions or chives.
