- 1 cup (110 grams) unsweetened Dutch-process cocoa, preferably Valrhona
- 1 cup (250 milliliters) whole milk
- 6 large egg yolks
- 1 cup (200 grams) sugar
- 1 teaspoon vanilla extract
- 1 1/3 cups (325 milliliters) heavy cream
- ½ teaspoon Ground Hot Red Pepper , or to taste
- In a bowl, whisk the cocoa into the milk until well blended. The mixture will be thick.
- In a saucepan, using a whisk or an electric hand-held mixer, whip the egg yolks, sugar, and vanilla until thick, pale yellow, and creamy. The mixture should form a ribbon when you lift the whisk. Whisk in the cocoa mixture.
- Set the saucepan over medium heat and cook, whisking constantly, until the mixture visibly thickens, coats the spoon, and registers about 180°F (82°C) on an instant-read thermometer, Do not allow it to boil or it may curdle. Transfer immediately to a bowl and let cool for 15 minutes, then whisk in the cream. Refrigerate until cold. Stir in the red pepper and taste. The pepper’s heat comes on slowly, so wait a moment before you decide to add more.
- Freeze in an ice cream freezer according to the manufacturer’s directions.
