*Green garlic is just simply young garlic, where it’s been harvested before it’s fully grown! It will look like a thicker/lighter scallion almost and you’ll use the white + light green parts. This is more common throughout farmers market’s vs. the grocery store. Spring onions are similar– they’re simply young onions! They’ll have a larger bulb than green garlic or scallions, but much smaller than a typical onion. All of this to say: you can’t mess this up! If it’s spring where you live or you have access to these varieties, great! If not, use a little extra leek or shallot, yellow onion, or even regular garlic cloves, sliced or smashed.
