Why it works: Butter and milk are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 81,283 recipes. Both carry (z)-4-heptenal, which smells biscuit, cream. The science ↓

Ingredients
Directions
In a saucepan, combine chocolate, sugar, butter, and milk.
Boil the mixture until it forms a waxy ball when dropped in cold water.
Pour the mixture onto a platter.
Stir vigorously before it cools until the grain is very fine.
Cut into squares once cooled.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Chocolate
- Provides the chocolate flavor and much of the fudge's richness.
- Sugar
- Sweetens the fudge and, as it crystallizes, helps set its texture.
- Butter
- Adds fat for a smooth, tender mouthfeel.
- Milk
- Supplies liquid that dissolves the sugar and adds creaminess.
The step that matters
Stir vigorously as it cools. Stirring during cooling forces sugar to crystallize into many tiny crystals, producing the very fine grain that makes fudge smooth rather than gritty. Stirring too early or too late changes the texture.
