Pour pudding into a buttered casserole dish and place on a baking sheet with sides. Cover the entire casserole and baking sheet with aluminum foil, leaving a corner open.
Place Pudding in oven and pour into the opening hot water to create a hot water bath. Fold down corner of foil and seal so steam doesn’t escape.
Bake for 45-60 minutes until Pudding is set.
