Are scallions the same as spring onions?
Scallions and green onions generally refer to exactly the same vegetable. With scallions, you’re generally using the attractive green leafy part of the plant (although the white part closer to the root tastes fine as well); it’s only the very bottom inch or so of the root part of the plant that you won’t use for cooking purposes. Still, don’t throw out those nubby remainders – if you pop the roots into a pot of dirt, and give them sunshine and water of course, the scallions will keep growing, and you’ll have access to fresh, free scallions whenever you need them.
