After the acquisition of your snails 3 to 4 days prior to cooking your escargot, they must be "cleaned". Place the snails in a white wood container with some corn meal, along with some fresh green parsley along with a little dill weed. Three or four days of this controlled and "clean" diet will solve the "off-taste" problems. The URL escargot.free.fr/eng/cooking.htm has some great recipes, but their suggested method of "cleaning" the snails is too much work for me.
