This is a quickie tip that I got from somewhere years ago and have used successfully ever since.
If you’ve ever tried to freeze meatballs or sliced garlic or ravioli in resealable freezer bags and ended up with a frozen lump of stuck together stuff that is difficult to separate for cooking, this is the solution for you.
Take a flat dinner plate and lay it on the counter. Fill your freezer bag with the items, but don’t dump them into the bottom like filling a grocery bag. Fill it flat in one layer, using the plate for support. Seal the bag, squeezing out as much air as possible and put the plate and bag in the freezer. Once the food is frozen, remove the plate. You can store the bag flat! And when you want to use just a bit, it is easy to break off the amount you want. What you see in the pictures is roasted garlic that I wanted to save. Whenever I need it, I break some off. It is easy to slice when it is frozen too!
