When I buy meat, I buy it in bulk packages, usually between six and seven pounds each. I weigh it on my handy kitchen scale (you do have a handy kitchen scale, don't you?) and divide it into 1 1/2 pounds portions. I usually cook one portion up right then, and freeze the remaining ones.
I put them into gallon sized freezer bags and press them flat, making sure the corners are filled. Easy as pie! I lay them in the freezer flat. When I need to thaw one, I place them in the sink and run a bit of hot water. They are thawed in just ten minutes or so!
