Never bought in bulk as I don't have the freezer space but i often freeze raw meat. There is no reason not to. I have a pork tenderloin 1 lb of best stewing steak, 2 bags of jumbo prawns a pack of tuna steaks and two sea bass in there at the minute.
I'm open to trying most meats and fish to be honest. I've had beef, lamb, pork, chicken, Ostrich, turkey, venison, boar, rabbit, pheasant, and wood pigeon. Fish wise I've tried Tuna, shark,Swordfish, monkfish, cod, mackeral, haddock, pollock, Salmon, Trout, Basa, lemon sole, plaice, Sardines I'm sure there are more.
