get a plastic tupperware container. put rock salt in there good amount with water. throw in your herring let them thaw. then pre plug them and keep them refrigerated cut plugged. I keep any where from 3-4 dozed pre plugged in the big container. then I have a little one that I use for the day I'm going fishing. use the same brine but add powdered milk to the one your gonna be using. do it the night before it keeps the flash. fresh herring plugged and thrown in brine is best
