I use the recipe that is on Mrs. Wages Pickling Lime container. It can probably be found at the grocery store with the canning good--like jars, lids, etc. You'll need that lime.
Briefly (as can be) I cut them up a tad LESS than 1/4 inch thick into a large non-reactive pot or big bowl--something that will fit in your frig. (with a plate on top you
can put other stuff on top of it).
Mix 1/2 cup lime with a gallon of water and pour over them. If you are doing a huuuuuuge amount in biiiiig bowl you can make more or this. Let this sit in frig overnight.
