Hard rolls fix again soft and crispy
The tip with the fridge, has already been described here. But what, if you had forgotten that the day before and the rolls are already hard?
If you place the bun on a glass of water and put it in the microwave for a minute, the steam of the boiling water pervades the whole bun and makes it soft again.
If you then roast it on the toaster, it will be crunchy on the outside and stay soft inside.
That would have been achieved even if you had wet it and put it in the oven for some time, but this variant is faster and uses less energy.
