Persimmon Upside-Down Cake
16 tablespoons unsalted butter
1/2 cup brown sugar
1 pound fresh Fuju persimmons, peeled, halved and pitted
2 1/4 cups all-purpose flour
3 teaspoons baking powder
1/4 teaspoon salt
1 1/2 cups granulated white sugar
1 1/4 teaspoons vanilla extract
3/4 cup whole milk
Pinch of cream of tartar
1 cup heavy cream
1 tablespoon confectioners’ sugar
Butter a 9-inch cake pan. Place the pan over medium heat and melt 4 tablespoons of the butter and brown sugar in the bottom of the pan. Overlap the persimmon slices on top of the melted butter and brown sugar.
Preheat the oven to 350°f . For the cake, sift the flour, baking powder, and salt together. Cream the remaining 12 tablespoons butter and granulated white sugar together in a bowl until light. Separate the eggs and add the yolks, one at a time, beating well after each addition. Add 1 teaspoon of the vanilla and mix well. Add the milk and the dry ingredients alternately to the batter, folding well after each addition. Beat the egg whites to form soft peaks. Add the cream of tartar and continue to beat until stiff peaks form. Fold the whites into the cake batter. Spread the batter over the persimmons and bake until a skewer inserted into the center comes out clean, 60 to 75 minutes.
Cool the cake for 10 to 15 minutes and run a knife around the edges of the pan to loosen it. Turn the cake over onto a serving platter and let it sit another 5 minutes. Remove the pan.
To serve, whip the heavy cream until soft peaks are formed. Sift the confectioners’ sugar on top of the cream, add the remaining 1/4 teaspoon vanilla, and fold together. Serve with the cake.
