Ingredients

Directions

Make the syrup

  1. In a saucepan, combine white sugar, brown sugar, corn syrup, boiling water, and salt.

  2. Cook the mixture until it reaches a brittle stage. Do not stir while cooking.

Combine and set

  1. Pour half of the syrup over the well-beaten whites of 3 eggs.

  2. Cook the remaining syrup for 5 to 6 minutes longer.

  3. Add the chopped walnuts just before pouring the syrup onto a platter.

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

What each ingredient does

White sugar
Provides the main sweetness and forms the firm, set structure of the candy as the syrup cools.
Brown sugar
Adds deeper caramel-like flavour and sweetness to the syrup.
Corn syrup
Interferes with sugar crystallization, keeping the candy smooth rather than grainy.
Walnuts
Add crunchy texture and nutty flavour against the soft candy.

The step that matters

Cook the mixture to the brittle stage without stirring. Syrup taken short of the brittle stage stays soft and will not set firmly, while overcooking makes it hard. Stirring can trigger sugar crystals, which make the candy grainy.

Swap the walnut

How well each one fits the dish's main ingredients (sugar, corn, syrup, vanilla):

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

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