This machine is my new best friend:
Originally used in our house for freezing meat during hunting season, crab meat in the summer and fresh fruit from nearby farms, it now freezes William's baby food.
I have been using this tray which makes 1 oz cubes:
Once I puree a fruit or vegetable, I freeze one tray's worth and keep any remaining puree in the refrigerator and use that first. The next day I pop out the cubes and put them into 3 inch bags I cut from the roll. I use the "manual seal" option to seal off one end before putting in the cubes. I usually do three because that is two feedings worth so it is easy for me to thaw.
Then, I use the "vacuum seal" to suck out all of the air and seal up the other side of the bag. And that's it! NO FREEZER BURN! After my other post about baby food, a few friends on Facebook told me the bad part was freezer burn. Well, this prevents it.
