This recipe appears in:Olive Oil Cake with Roasted Grapes & Chocolate Ganache
This elegant dessert marries three components: a moist olive oil cake made with cornmeal and flavored with orange, sweet olive oil-roasted grapes, and a thin coating of bittersweet chocolate ganache.
Why this recipe works
- Slowly roasting the grapes in the oven concentrates their sweetness.
- Grapes and chocolate actually make a wonderful pairing, especially when that chocolate is dark.
- Polenta gives the crumb texture
- Fresh orange juice and zest add a freshness to the cake and also provides a nice contrast to the chocolate ganache.
- Fruity olive oil rounds out the flavor of the cake and adds a subtle savory element
- For the Roasted Grapes:
- 2 cups seedless purple grapes, stemmed
- 1 teaspoon olive oil
- For the Cake:
- 1/2 cup plus 2 tablespoons stone ground cornmeal
- 1/2 cup all purpose flour
- 1/2 teaspoon baking powder
- 1/2 teaspoon salt
- 4 eggs, lightly beaten
- 3/4 cup sugar
- 1 tablespoon zest and 1/4 cup fresh juice from about 1 medium orange
- 1/2 cup extra virgin olive oil
- For the Ganache:
- 5 ounces bittersweet chocolate, finely chopped
- 1/2 cup heavy cream
- 2 tablespoons granulated sugar
- 2 tablespoons water
Roast the grapes: Adjust oven rack to middle position and preheat oven to 325°F. Place grapes on baking sheet and toss with olive oil. Roast until soft and shriveled, about 1 hour. Let cool completely.
Make the cake: Grease cake pan with oil or butter. Increase oven temperature to 350°F. In a small bowl, whisk together cornmeal, flour, baking powder, and salt; set aside.
In a large bowl, whisk together eggs and sugar until lightened in color, about 3 minutes. Whisk in orange zest, followed by olive oil and orange juice. Add dry ingredients to the bowl and whisk until no clumps are left. Stir in roasted grapes.
Pour batter into prepared pan and smooth top, tapping pan to make sure grapes are evenly distributed. Bake until a cake tester inserted into the middle of the cake comes out clean, 50 minutes to 1 hour. If top is starting to get too brown, cover with foil and continue baking.
Let cake cool for 15 minutes then release from springform pan to continue to cool. Meanwhile, make the ganache.
Make the ganache: Place cream, sugar, and water in a medium saucepan over medium heat. When cream comes to a boil, take off heat and add in chocolate, stirring until chocolate is completely dissolved and mixture is smooth.
Place cooled cake on a cake rack set over a baking sheet or other large dish. Pour glaze over the cake (there will be overflow) and smooth over top and sides using an offset spatula. Transfer cake to refrigerator and chill until glaze is set, about 20 minutes. Keep cake in refrigerator, loosely covered with plastic wrap, if not eating right away.
