Leek

Remove the outer leaves. Split the leek almost in half, stopping just before the root. Allow the leeks to sit for a few moments in a bowl under running water in order to dislodge any dirt and possible infestation. Then, under running water, each leaf of each leek must be rubbed. This is best achieved by taking the leaf between your index finger and thumb (with your thumb on top) and running them the full length of the leaf. Check all areas to ensure that nothing has been missed.
