I have tryed this with mushrooms and fish, it works great. Take cookie sheets that will fit in your freezer. Place your filets (alternating) with the skin side down. Place in freezer. After about 20-30 minutes (depends upon your unit) pull the sheet out, use spray bottle, lightly spray and place back in freezer. Do this twice and then let freeze overnite. Remove and vacum pack and place back in freezer. All processing ships flash freeze their catch and then package. Try it, it works for me. If I am going to eat within a month, then I will freeze in water.
