Sold in small bunches of 6-12 depending on the size of the scallions.
Green onions, also known as scallions, are a member of the Allium family, which includes garlic, onions, leeks, and shallots. Green onions grow in clumps and develop green, hollow tube-like leaves. Although the term green onion is used for several different types of onions, the white base of true scallions has straight sides versus rounded (which distinguishes the beginnings of a bulb developing). There are usually short off-white root threads that protrude from the bottom of the white end.
One of the wonderful things about scallions is that they’re mild enough to be eaten raw or only slightly cooked, which preserves their crisp texture.
