Maple Walnut Buttermilk Ice Cream
Total Time: 30
Yield: about 5 cups
- 1-3/4 cups heavy cream
- 1-1/4 cups buttermilk
- 5 egg yolks
- 1 cup maple syrup, divided
- 1/8 teaspoon salt
- 1 cup walnuts, chopped and toasted
Instructions:In a saucepan, heat cream and buttermilk until it steams; then remove from heat. Meanwhile, beat egg yolks with half the maple syrup until pale and fluffy, about 3 minutes. Pour 1/2 cup of hot cream/buttermilk mixture into egg mixture, whisking as you go; then transfer it all back to the pot to create a loose custard.
Stir in remaining maple syrup. Heat custard on medium setting, stirring continuously, until it reaches 175° on an instant-read thermometer (this is the point at which it will thicken noticeably). Remove from heat, stir in salt, and pour through a strainer into a bowl. Place in refrigerator to chill to 35°-40°, about 6 hours or up to overnight. (You may speed up this process by stirring the custard over a bowl of ice.)
Pour mixture into your ice-cream maker, leaving 3/4 inch at the top to allow for expansion, and prepare according to freezer instructions. Add walnuts during final 5 minutes of chilling.
