You see, I like my bananas really hard, still a little bit green - and it's only on day 1 of buying them they are like that. They ripe super quickly here and I never have time to finish the bunch before they've gone all mushy. Since there is no secret to stopping them from ripening, we've been baking a lot of banana muffins etc with our black bananas.
Well, that was before!
I decided to give this Banana Bag thing a try and ordered one. You are supposed to keep your bananas in it, in the fridge, and the perfect amount of insulation and air stops the flesh over-ripening, while keeping the skin warm enough to prevent it from blackening. And it works!!
