Do you do anything to prepare clams before cooking them, like letting them sit in fresh clean water? The reason I ask is that we pulled up some clams a month or two back from the beach off our back porch and they had a discusting smell. It smelled like the sand I got them out of. Kind of like decay. I am correct in guessing that it in not like this at other spots correct? Any suggestions on where to find some better picks in Juneau?
