defrost/reheating frozen doughnuts
I was given several very delicious doughnuts (crullers from Daily Provisions), so many that I had to freeze a few. I'm hoping that when defrosted that they will still have a lovely custardy interior (almost like a canele). Should I defrost in the refrigerator, and would it be harmful to reheat in an oven? There is a cinnamon sugar coating, and I wouldn't want it to melt. It would also be nice to crisp up the exterior.
Thanks for any suggestions!
