My mother taught me a neat trick, that we have called "flash freezing". Essentially, it is freezing an item for a short length of time, just until it is solid. This allows you to manipulate the item with greater ease.
For example, I flash freeze bacon in single layers (not overlapping) on a cookie-sheet, so that I can lift off the slices into my Tupperware bacon keeper. Once frozen, I quickly return the bacon slices to the freezer, and now if I need just 3 or 4 slices, I can easily remove just what I need without defrosting the entire package of bacon. This makes it really easy to add a little bacon to whatever you're cooking.
I also have done this with blueberries, strawberries, peaches, etc. The great benefit is being able to take out the items without them being frozen in a mass. It is great for making muffins, and helps a lot if you just want to sprinkle a few berries into something (like pancakes).
Lemon slices also work really well. I pick up bags of lemons when they're on sale, slice them, flash-freeze them, and then I have lemon slices for tea or ice-water all the time.
This trick has many applications, and I have found it to be a simple way to freeze items that otherwise I wouldn't even think of freezing.
Hope it's a helpful trick for you!
