What is the best way to reheat the pudding? Would like to reheat it the next day.

Hello Deb, I know this answer may be a bit late but I hope it is useful in the future! The best way to reheat any kind of molded pudding is to cover the dish with aluminium foil, and then place within a deep oven-safe dish. Then you'll want to pour boiling hot water into the dish until it comes about halfway up the side of the pudding dish. Then cover the whole lot with more foil. Pop that into the oven at 350 degrees Fahrenheit and give it about 30 minutes, refill water if necessary, and then another 30 minutes. Hope this helps!
