This is a video recipe for easy-to-make sweet potato that doesn't require straining. Prepare about 300g of sweet potato with the skin on, peel it, and heat it in the microwave until soft. Then, add heavy cream, brown sugar, and unsalted butter, and heat it in the microwave again, mixing until it becomes a smooth paste. Finally, add a whole egg and mix well, then pour it into a loaf pan, brush the surface with egg yolk if desired, and bake in the oven. By making extensive use of the microwave, the cooking time is shortened, and you can easily enjoy authentic-tasting sweet potato. The fluffy texture and buttery aroma will whet your appetite.
