Trim the leek root end off and the tough dark green stem. Cut only the fibrous part, and keep the edible softer parts of your leek.
Discard damaged outer layer too.
Cut into your leek lengthwise into the dark green leaves so to create a cross design. This is to wash out the mud from within the leek. Cut as deep as need be if you still see mud.
Rinse your leek to get rid of impurities and pat dry to soak in excess water.
Cut your leek crosswise into 3 manageable pieces.
