Introduction: Clean Leeks Properly

Clean your leeks easily and efficiently by following this simple step by step Instructable.

Leeks, a member of the onion/garlic family, are a delicious addition to most meals and a common base flavor in stocks. Leeks are grown and used primarily for their creamy tender white base, which is produced by piling soil up around the base of the leeks as they are growing. This method of piling soil prevents the sun from adequately shining on the base of the leek, leaving a longer more supple white base. Due to the constant piling of dirt, leeks are often filled with sand and dirt between their many onion layers. Their numerous tightly stacked layers can be intimidating to clean, but it really couldn't be easier.

There are two primary methods for cleaning leeks. The method you choose will depend entirely on how you will be using the leeks in your cooking. I will cover a cleaning method for chopped, diced, or sliced leeks first and then cover a washing method for whole leeks. 

Step 1: Remove the Root

No matter which method you will be using to clean and wash your leeks, you will need to cut off the root end of your leeks. Sometimes your grocery store or farmers market stall will have already cut off the majority of roots leaving only the root end. You will still want to cut this section off. 

If you are planning on using your leeks as chopped, diced or sliced, cut off 1/4" (0.625 cm) from the base of your leek. This should not only remove your roots but also the root end. 

If you are planning on using your leeks as whole leeks, you'll want to cut less than 1/4" of the base off of your leek. You'll want to keep as much of the connective base layers as possible to keep your leek whole. You do still want to remove the rough root base. 

Step 2: Remove the Dark Green

Remove the upper dark green portion of your leek by cutting it with your knife right where the leek starts to fan out.

This dark green portion of the leek is often removed as it is generally more fibrous, tougher, and takes longer to cook till it is soft and tender. You can save it and use it to create and flavor stocks and soups. I usually like to save them by placing them in a plastic ziplock or tupperware and freezing them until I'm ready to use them. 

Step 3: Cleaning Leeks to Be Chopped

If you are going to be using chopped (diced, sliced) leeks in your culinary adventures, it is easiest to clean them and wash away the dirt once they have already been chopped. 

Steps:
  1. Cut your leek in half lengthwise. 
  2. Slice your leek crosswise to your desired width. This will allow all of the leek layers to separate and release the dirt and sand. 
  3. Place your sliced leeks into a bowl. 
  4. Fill your bowl of leeks with cold water. 
  5. Using your hands, swirl your leek slices around in the water. Break up any layers that are stubbornly sticking together. Continue to wash your leeks in this manner until you feel the dirt and sand have been dislodged from your leeks. The sand and dirt should sink to the bottom of the bowl and the leeks will continue to float at the top.
  6. Using a slotted spoon transfer your leeks from your water bath to a colander. Allow your leeks to dry. You do NOT want to pour your leek water bath into the colander since the dirt you have dislodged will come with the leeks. 
If you do not want to wait for your leeks to dry in step 6, you can transfer your leeks to a salad spinner after step 6.

Step 4: Cleaning Whole Leeks

Occasionally recipes call for whole leeks, which can be a little harder to clean.

Steps:
  1. Peel off the outermost layers of your leek. 
  2. Insert the tip of your knife an inch away from the root end of your leek. Slice your leek in half lengthwise by moving the tip of your knife to the end of the dark green section. By leaving once inch of white stalk intact, you'll guarantee that your leek will stay whole while simultaneously allowing access into the many layers of your leek. 
  3. Fan your leek with your fingers so that multiple layers are exposed. 
  4. Rinse under cold water with the dark green end of your leek pointing down. This will allow for the dirt and sand to fall out of the leek. Continue to fan and manipulate the layers of the leek with your fingers as you rinse it under the cold water. 
  5. Allow to dry. 
You're done! You've got whole washed leeks on your hands. Whole leeks are great barbecued!

Sorry, I just saw the notification for your comment. I don't know about your area but they're very plentiful here in the Spring. I find them along maple ridges.

regarding the step 2: I usually cut only the upper dark green leaves because there is delicious light-green part under it.
