L.A. Times Test Kitchen tips: Cleaning leeks
A member of the onion family, leeks look like large scallions with a thick base, or stem. Because the white part of the base is prized in cooking, farmers mound dirt around the leeks to keep out the sunlight, extending the white.
Unfortunately, a lot of that dirt and grit ends up in between the layers of the leeks as they grow.
To clean a leek, peel and discard any old outer leaves, then trim the leek of the dark green leaves and base, reserving the white and any of the very light green base. Trim the root end, then halve the leek lengthwise. Rinse the leek under cold, running water, feeling between the layers to loosen and dislodge any dirt or grit. Finally, slice and use as desired.
Often, after I'm done slicing the leek, I'll rinse the pieces in a colander under cold water. Just to make sure all the dirt is gone.
