When I have bananas that have ripened to the point that they are ready for banana bread....
(usually because no one thought to eat them before they got so ripe)
I peel them and put them in a Foodsaver bag - 3 bananas to a bag - vacuum them in the food saver...
then mash them by kneading the bag... and toss them in the freezer.
When I'm in the mood for banana bread, I pull out a package.
Perfect number of bananas for my recipe!
