Yet another thing I learned from the The Complete Italian Vegetarian Cookbook: how to cut and clean leeks. Leeks have a very mild flavor compared to a regular onion and make a great soup or stock. A leek looks like a giant overgrown scallion.
The white portion is what’s commonly eaten. To encourage that portion of the stalk to stay white and tender, dirt is piled up around the stalk as it’s growing. The result is dirt between the layers of the leek where you can’t see it from the outside. To clean a leek, first cut off the white roots from the bottom end:
Next, trim the dark green leaves from the top and cut the leek in half:
Very likely, dirt will be hiding between the layers of the stalk:
To remove the dirt, separate the layers a little without pulling the leek completely apart while running the leek under water in the sink. Now the leek is ready to be chopped:
Now you know how to get the leek clean and ready to use. Enjoy it in a soup or stock.
