The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

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

What each ingredient does

Sugar
Provides sweetness and the bulk of the solid structure once the mixture cools and sets.
Glucose
Interferes with sugar crystal formation, keeping the fudge smooth rather than grainy.
Milk
Adds moisture and milk solids that contribute richness and a softer texture.
Fondant
Adds fine sugar crystals that help the fudge set creamy and smooth.
Blanched roasted peanuts
Add crunch and roasted flavor that contrast with the smooth fudge base.

The step that matters

Continue stirring until the mixture is thick and cool. Stirring while the sugar cools encourages many fine crystals to form, giving a smooth texture. Stopping too early or letting it set undisturbed can leave the fudge coarse or grainy.

Swap the peanut

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

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

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