Question: how can you ripen bananas for banana bread?
Answer: Poke unpeeled bananas all over with a fork or knife, then put them on a paper towel or plate and microwave on high for 30 seconds at a time, repeating until they're as soft as you want them. They won't be quite as sweet as the oven-ripened versions, but they'll be mashable for your muffins and quick breads.
