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

What each ingredient does

Granulated sugar
Provides the sweetness and, when boiled and cooled, forms the fudge's crystalline body.
Milk
Supplies moisture and milk solids that give the fudge a softer, creamier texture.
Unsalted butter
Adds fat that makes the fudge smooth and rich in mouthfeel.
Broken walnuts
Add crunch and a nutty flavor that contrasts with the soft fudge.

The step that matters

Beat the mixture until it loses its gloss and holds its shape. Beating after the boil lets sugar crystals form in a fine, smooth network. If the mixture is beaten while too hot or not long enough, the fudge stays soft and grainy or fails to set; beating too long while warm can make it stiff and hard to pour.

Swap the walnut

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

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

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