I cook peppers quite a fair bit and I also put them in the porridge for my child. However, I usually use half a pepper in the porridge. What do I do with the balance? I keep it in the fridge to be used the next time. Usually the leftover pepper would turn wrinkly after a few days. A while ago I came across a cute pepper-shaped container which helps to keep the air and light out of cut peppers. The Pepper Saver is perfect for keeping the cut peppers stay fresh longer.
