Ideally the bananas should have yellow skins (no green!) with an even smattering of brown freckles. But we know that the urge for a fresh loaf of banana bread can be overwhelming at times, and you just can't wait a day or two for the bananas to ripen on their own. So get ready for instant gratification: We have a trick for ripening bananas for use in baking recipes that takes almost no time at all.
