Sounds like a whole lotta bother, too. Banana bread is the easiest thing in the world to make. They have to make it complicated, and dirty up 100 more dishes to boot.
I myself buy discounted bananas, peel them, and freeze them.
And then when I need potassium, I take a couple and blend them in with orange juice.
The blender here gets more of a workout than the stove, and better yet, the blender runs on electricity, not natural gas, so it's safer.
I know, I know; I'm odd.
