I have the best memories of rotten banana days in my house growing up.
You know what I mean... you were at the grocery store and decided to buy bananas. But you don't really like bananas that much. So they end up sitting there for a week (or two or three...) and they start to get too gross, even for a smoothie.
But the best thing about almost-rotten bananas is that they're great to bake with. My mom used to make this DELICIOUS banana bread on those rotten banana days, and I remember the smell of fresh baked bread filling the house.
Banana bread is really good the first day when it comes out of the oven warm, but its REALLY GREAT for the next several days when you cut yourself a slice or two, spread a little butter on it and throw it in the toaster oven.
