Racines Cake

• Cocoa powder, for preparing the pan
• 10 ounces (280 g) bittersweet or semisweet chocolate, chopped
• 1/2 cup (4 ounces/115 g) salted butter, cut into pieces
• 1 tablespoon freshly brewed espresso
• 1/2 teaspoon vanilla extract
• 6 large eggs, separated, at room temperature
• 1/4 cup (50 g) plus 2 tablespoons (30 g) granulated sugar
• 2 tablespoons (20 g) cocoa nibs (optional)
• Powdered sugar, for dusting the cake (optional)

1. Preheat the oven to 350F (175C).
2. Butter the bottom and sides of a 9-inch (23-cm) springform pan, dust it with a bit of cocoa powder, and tap out any excess.
3. In a large heatproof bowl, combine the chocolate, butter, and espresso.
4. Set the bowl over a pan of simmering water and stir occasionally until the mixture is melted and smooth.
5. Remove the bowl from the heat and stir in the vanilla.
6. In a stand mixer fitted with the whip attachment, whisk together the egg yolks and the 1/4 cup (50 g) granulated sugar on medium-high speed until the mixture is light and creamy, about 1 minute.
7. In a clean, dry bowl and with a clean whip attachment, whisk the egg whites on low speed until they begin to hold their shape.
8. Add the remaining 2 tablespoons (30 g) granulated sugar and whisk on high speed until the whites hold soft peaks.
9. Fold the beaten egg yolks into the melted chocolate mixture, then fold in half of the whipped egg whites.
10. Fold in the remaining whites, mixing just until there are no visible streaks of egg whites.
11. Dont overfold.
12. Scrape the batter into the prepared pan, sprinkle with cocoa nibs, if using, and bake until the cake feels as though its just barely set in the center, about 25 minutes.
13. It shouldnt feel too firm.
14. Let cool completely.
15. Run a knife around the sides of the cake to help loosen it from the pan.
16. Release the sides of the pan and dust the cake with powdered sugar, if using.
17. The suggested accompaniment at Racines was whipped cream scented with orange flower water.
18. But the cake also goes well with a scoop of ice cream and a dousing of Bittersweet Chocolate Sauce (page 243).
19. The cake is best served the day its made, although it can be kept for up to 2 days at room temperature.
20. Cocoa nibs can be found in well-stocked markets or purchased by mail order (see Resources, page 270).
