Petehboro Ice Cream

Ingredients

Directions

Make the base

  1. Steep the vanilla bean in a little of the cream, breaking and scraping it to release the flavor.

  2. Mix the steeped cream with the remaining cream and sugar thoroughly.

Freeze and finish

  1. Pour the mixture into a packed ice cream freezer and freeze it.

  2. Rinse the vanilla bean pod, let it dry, and use it to flavor boiled custard.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Cream
Provides fat and richness, which give the ice cream its smooth, creamy body.
Granulated sugar
Adds sweetness and lowers the freezing point, keeping the ice cream soft rather than rock-hard.
Vanilla bean
Supplies the vanilla flavor, released when the bean is steeped in the cream.

The step that matters

Freezing the mixture in a packed freezer. The freezer must be packed well in ice and salt so the mixture chills fast. Slow freezing forms large ice crystals, leaving the texture coarse and grainy.
