Overripe bananas go in the freezer, not the bin
Black bananas are the best base for baking and smoothies.
1
The darker the banana, the sweeter it is: the starch has turned to sugar. Perfect for baking.
2
Peel the bananas, cut into pieces or halves and freeze in a bag — up to 3 months.
3
For banana bread and muffins, thaw them and use them with the liquid they release.
4
Frozen chunks are the base for thick smoothies and banana "ice cream" with no sugar or ice.
