Mammaw's Pineapple Upside-Down Cake
1/2 cup unsalted butter
Preheat oven to 350 degrees. Over a low flame, melt the unsalted butter in a cast-iron skillet. Spoon in the brown sugar. Turn off the heat.
Arrange the pineapple slices over the brown sugar mixture. Cut leftover slices in half, and use them to line the sides of the skillet, cut sides facing in. Stick a cherry in the center of every pineaple circle. Press the pecan halves between the pineapple slices.
In a large bowl, combine the flour, baking powder, and salt, then run your hands through it. Or use a sifter. Plug in an electric mixer and beat the egg yolks until they are thick. Very slowly, add the sugar. Spoon in the flour, baking powder, and salt. Add the vanilla.
Pour the mixture of egg whites into a deep bowl. Beat them with a mixer on high. When stiff peaks form, stop beating. Using a rubber spatula, fold the whites into the batter. Gently spoon the batter over the pineapple. Bake 50 minutes. Remove from the oven and invert, without cooling, onto a serving plate. Being careful not to burn yourself.
