To be honest, I always thought a scallion and a spring onion were two different names for the same vegetable. Turns out, I was wrong. A true spring onion has a larger bulb than a scallion (though still smaller than a standard onion) and is only available during—you guessed it—the spring. It has a mellower flavor than a regular onion and can be grilled or roasted whole, thinly sliced and marinated, or battered and fried into delicious onion rings.
Here’s a quick guide to 4 similar but different types of onions you’re likely to encounter at your farmers’ market right now.
