What Do I Do With Unripened Bananas?

We use a lot of bananas in our house. I wish they didn’t have to travel so far.
I hate it when I get to the store and all the bananas are green. Even worse is that most stores throw out perfect, ripe, spotted bananas — excellent for cooking, smoothies, and replacing sugar in a lot of recipes.
It’s Sunday and I’m going to make my kid healthy, fruit-sweetened banana muffins, so I needed to ripen my bananas quickly!
I have a bunch in a paper bag, along with a ripe apple. The ethylene gas released from the apple, along with the closed paper bag both speed up ripening, but I need ripe bananas now.
What to do?
Put unripened bananas in the oven at 300 degrees Fahrenheit for 15 minutes. Problem solved!
