Why it works: Milk and vanilla are a kitchen classic. They rank in the top 5% of all ingredient pairs, and cooks put them together in 19,187 recipes. Both carry ethyl caproate, which smells fruity, apple peel. The science ↓
Chocolate Peppebmints
Ingredients
Directions
Make the peppermint centres
Beat the egg white with confectioner's sugar and add 5 drops of oil of peppermint until thick enough to mold.
Chill the mixture before covering it with melted chocolate.
Make the fudge layer
Melt the butter in a saucepan, then add sugar and milk.
Heat to boiling, then add chocolate and stir until melted.
Boil slowly for 13 minutes, then remove from heat and add vanilla.
Set the dish in cold water and beat until it thickens.
Pour into a buttered pan and mark into squares when slightly cooled.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg white
- Whips into a thick, stable base that holds the peppermint centres together.
- Confectioner's sugar
- Thickens the whipped egg white into a moldable mixture while adding sweetness.
- Butter
- Adds fat and richness to the fudge layer, giving it a smooth, tender texture.
- Sugar
- Sweetens the fudge and helps it set firm as the mixture cools and thickens.
- Milk
- Provides moisture and milk solids that soften the fudge into a creamy texture.
- Chocolate
- Supplies flavour and a melted coating over the centres, then enriches the fudge.
The step that matters
Boil slowly for 13 minutes. Boiling the sugar and milk mixture for the set time drives off water and concentrates the sugar. Too little cooking leaves the fudge soft, and too much makes it hard and grainy.
Swap the peppermint
How well each one fits the dish's main ingredients (egg, sugar, butter, milk, chocolate, vanilla):
- Cinnamonfits better
- Nutmegfits better
- Peppermintthe original
- Clovefits about as well
Fit is the average pairing score against egg, sugar, butter, milk, chocolate, vanilla. Candidates are from the same food group and used in at least 100 recipes.
