So I froze dem bananas yesterday, when I get em out, they're like all black and squishy, and when I ate dem, taste like some kinda gooey Mush but cold.
This happens when they are frozen still in the peel. The banana peel will blacken but the fruit will stay okay.
When I freeze bananas as ingredients for smoothie drinks I peel them and slice them up and then store them in ziploc bags. The bananas retain their yellow color and are perfect for tossing into my blender or snacking on if I want to cool down.
