Rice pudding is a delectably creamy and sweet dessert. I've always done the "cheater rice pudding" where I take cooked rice, add milk or cream, add some sugar or honey and cook it down a bt in a saucepan. Personally, I like mine with raisins mixed in and a little cinnamon sprinkled on top, but I know that's not for everyone.
Rice pudding is pretty ubiquitous. Would you like Bulgarian rice pudding? Indian? Egyptian? British? Or do you have a rice preference? Thai rice pudding can be made with black rice , sticky white glutinous sweet rice, or with red rice. Or maybe you want to pretend something made with cream and sugar is healthy and use brown rice. You could probably use any kind of rice you want. (Again, I vote for whatever leftover rice you have on hand.)
But then do you want to bake it? Or just go with stove top? And then would you like to add a flavor, maybe coconut or vanilla? Raisins? Nuts? Ahhh!!! Too many choices and all just for rice pudding!
