Freezing Berries and Bananas
We use a ton of bananas in our house. I bet we go through two bunches a week. I try to head to town just once a week and that means buying ahead on bananas and hoping they don't ripen too fast or that all they have are the greenest bananas you've ever seen. Sometimes if I am lucky the stores have bagged bananas at a lower price, like $1.99/bag or the the other store has them for 39 cents/lb which is about 20 cents cheaper than regular price right now. Bags are about 8-9 lbs. They may look speckly but so far they are all still very firm.I take the peel off and hunk them. Place them upright on a freezer paper lined jelly roll pan and put them in the freezer. When they are thoroughly frozen, at least all day or I wait until the next day, I put them in a freezer ziploc bag for use. I tried the first time to see if they would turn brown and they didn't so I have frozen some several times since. We use them in smoothies, and protein shakes. No need for ice (filler) or worrying about the bananas getting too soft or if the store only has green bananas.
I also freeze strawberries on sale (or hopefully soon from our own patch) and the wild black raspberries we have in our backyard.
Last year I bought a flat of cherries and blueberries and did the same. I used my vacuum seal bags to keep them crystal free in the freezer.
