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

What each ingredient does

Sugar
Provides sweetness and, when cooked and cooled, forms the fudge's fine crystalline structure.
Butter
Adds fat for a smooth, rich texture and helps keep the fudge tender.
Milk
Supplies liquid and milk solids that give the fudge a creamy body and flavor.
Ground chocolate
Provides the main chocolate flavor and contributes to the fudge's color and body.

The step that matters

Stir in vanilla and lemon extract until nearly cold. Stirring while the mixture is still hot lets sugar crystallize unevenly, making it grainy or sugary. Waiting until it has cooled nearly to lukewarm lets the sugar form fine, smooth crystals for a creamy texture.

Swap the lemon

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

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