Caramel Nut Ice Cream

Ingredients

Directions

Make the caramel

  1. In a small saucepan, combine two-thirds of the sugar and place over medium heat, stirring constantly until melted and the color of maple syrup.

  2. Add the chopped walnuts to the caramel and pour into a lightly buttered pan to cool.

  3. Once cool, pound the mixture in a mortar and strain through a fine sieve.

Make the custard

  1. In a separate bowl, make a custard by whisking together the egg yolks, remaining sugar, milk, and salt over low heat until thickened.

Combine and freeze

  1. Stir in the caramel mixture, vanilla extract, and whipped heavy cream until well combined.

  2. Freeze the mixture until firm.

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

What each ingredient does

Egg yolks
Thicken the custard and add richness to the ice cream base.
Sugar
Sweetens the base and, caramelized, adds deep toasted flavor.
Heavy cream
Adds fat for a smooth, creamy texture in the frozen result.
Milk
Forms the liquid base of the custard.
English walnuts
Add crunch and a toasted, nutty flavor to the caramel.

The step that matters

Cooking the caramel to maple syrup color. Sugar darkens quickly once it melts, so stirring constantly and stopping at maple syrup color prevents bitterness from over-browning while still developing deep caramel flavor.

Swap the walnut

How well each one fits the dish's main ingredients (sugar, milk, cream, vanilla, egg):

  1. Almondfits better
  2. Chestnutfits better
  3. Hazelnutfits better
  4. Walnutthe original

Fit is the average pairing score against sugar, milk, cream, vanilla, egg. Candidates are from the same food group and used in at least 100 recipes.
