Here's an easy recipe for a melt-in-your-mouth cheesecake using sweet potatoes. Peel and cook sweet potatoes, then roughly mash them. Add brown sugar, cream cheese, eggs, and heavy cream with 40% milk fat in that order and mix well. No cake flour is used; the milk fat in the heavy cream creates a buttery richness and smooth texture. Pour the batter into a mold and bake in a water bath at 200 degrees Celsius for 40-45 minutes after preheating the oven to 210 degrees Celsius. Chilling in the refrigerator for 2 hours will result in a melt-in-your-mouth softness, while chilling for 4 hours or more will chill it thoroughly, allowing you to enjoy different textures. It's easy to make and hard to fail, so even beginners can make a delicious cheesecake that tastes like it came from a bakery. This is a perfect treat for your home cafe or as a gift, making the most of the flavors of autumn.
