Most of the time, people will tell you to rinse leeks scrupulously to get rid of all the dirt and sand that collects between the leaves. I don’t trust this method, since it seems the dirt really likes to hide. I saw Rachael Ray use this method once, and it works better than any other way I have tried.
how to cut and clean leeks
1. Cut off roots and dark green portion of leeks and discard. Cut leeks longways down the middle.

2. Place on the cutting board, cut side down, and slice into pieces of desired width. Place in a large bowl and cover with cold water. Use your hands to separate the rings. Let sit for a few minutes until all dirt, sand, and grit falls to the bottom of the bowl.

3. With your hands or a slotted spoon, carefully remove leeks and dry off on a paper towel.

I did this last night but put the chopped leeks into a colander that was resting inside a big bowl filled with water. So the chopped leeks were kind of swimming in the bowl of water but I could just lift the colander out at the end and the dirt was at the bottom of the bowl.
Lynn–Fantastic idea!!
[...] 1. Cut off the roots and the dark green portion of the leeks. Cut them down the middle longways, think hot dog bun. Place cut side down on board and slice all the way down every ¼-½”. Place in a large bowl with cold water, separating pieces with your fingers. Let sit until debris fall off. (Good visual tutorial can be found here.) [...]
