Peach Polenta Cake

Preparation

1. Step 1

   Heat oven to 300 degrees. Generously butter the bottom and sides of a 9-inch round cake pan and line the bottom with parchment paper. Cut one long strip of parchment paper to line the sides of the pan so that the paper reaches all the way around the pan with no gap at the seam, and stands about 3-inches high.

2. Step 2

   Place 1 cup/200 grams of the sugar in a saucepan with just enough water to cover, stir well and place over medium heat. When sugar turns the color of maple syrup, take off the heat and add 2 tablespoons/35 grams of the butter. Swirl to incorporate and pour into the cake pan. Place the fruit flesh-side down in a single layer all over the caramel, cutting a few pieces smaller if necessary to make it all fit. You can cram the fruit; it will shrink as it cooks.

3. Step 3

   Add almonds and polenta to a food processor and process until fine, then set aside in a large bowl with the flour, salt, baking powder and lemon zest. In the same food processor, cream the remaining butter and sugar. Add eggs one at a time, making sure each is emulsified before adding the next. Scrape the mixture into the bowl with the flour mixture and fold into the ingredients until smooth. Spoon the batter on top of the fruit and even out the top. Bake for about 2 hours, or until the the top is golden in color, crackled and firm to the touch. Set the cake pan on a rack to cool.

4. Step 4

   Once the cake has completely cooled, loosen the sides with the tip of a knife and flip it over in one quick motion, directly onto a serving platter. Holding onto the upside down cake pan and the platter at the same time, shake and bump the pan a little, if necessary, to release the cake, before lifting the pan away. Gently peel away any parchment paper. Slice and serve as is, or with a little crème fraîche on the side.
