How to wash leeks

How to wash leeks - cut right through leek lengthwise starting from about 1" from white bulb end to top of leek. Turn the leek so that you have one of the uncut sides uppermost and do the same again - you will be left with four leaf sections. With leek pointing downwards, run under cold water opening the leek leaves slightly to remove all grit. Believe it or not, although leek leaves are quite tightly packed, grit gets down between the leaves.
