what are leeks
Leeks are root vegetables that look quite similar to onions, to which they are related. Their flavor is onion-like but much milder. People who avoid this vegetable because they don't like onions should try them â their flavor is mellow and not overpowering, and many onion-haters enjoy them. Unlike onions, leeks don't form much of a bulb on the end of the root. Instead, they remain cylindrical, with perhaps a slight bulge at the end.
