Because bittersweet chocolate is high in pure chocolate (at least 35 percent cocoa solids), it's best used when a deep chocolate flavor is called for. It's also a great eating chocolate. Semisweet chocolate, which has more sugar and fewer cocoa solids than bittersweet, can often be substituted in recipes without significantly affecting the flavor or texture.
- 4 large egg yolks
- 4 tablespoons sugar
- 2 cups heavy cream
- 8 ounces bittersweet chocolate, melted
- 1 teaspoon vanilla extract
In a medium saucepan, whisk together egg yolks, 2 tablespoons sugar, and 3/4 cup heavy cream. Cook over medium-low heat, stirring, until mixture coats back of spoon, 3 to 4 minutes (do not boil). Remove from heat; whisk in melted chocolate and vanilla. Strain into a bowl; chill until cool.
With an electric mixer, beat remaining 1 1/4 cups heavy cream with remaining 2 tablespoons sugar until stiff peaks form. Stir 1/3 of whipped cream into cooled custard mixture, then gently fold in the rest with a rubber spatula.
Spoon into serving dishes; chill, covered, at least 30 minutes and up to 3 days. Bring to room temperature before serving.
