- 1 cup sugar
- 2 teaspoons black peppercorns, crushed
- 2 teaspoons cornstarch
- 1 1/2 cups whole milk
- 2 cups whole-milk Greek-style plain yogurt
- Equipment: an ice cream maker
- Heat sugar and pepper in a 2- to 3-quart heavy saucepan over medium heat, stirring with a fork to heat sugar evenly, until it starts to melt, then stop stirring and cook, swirling pan occasionally so sugar melts evenly, until it is pale golden. Remove from heat.
- Whisk together cornstarch and milk, then add to caramel with 1/4 teaspoon salt (mixture will bubble and steam). Simmer, stirring, until caramel has dissolved and mixture is slightly thickened, 2 to 4 minutes. Strain through a fine-mesh sieve into a bowl, then whisk in yogurt. Chill until cold, about 8 hours.
- Freeze in ice cream maker, then transfer to an airtight container and put in freezer to firm up.
