Why it works: Milk and butter 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 ↓
Vassar Fudge
Ingredients
Directions
Make the fudge
In a saucepan, combine brown sugar, chocolate, milk, and butter.
Boil the mixture, stirring to prevent burning, until it hardens when dropped in cold water.
Remove from heat and stir in shredded coconut.
Set and cut
Pour the mixture onto buttered tins.
Once cool, cut into squares.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Brown sugar
- Provides sweetness and bulk, and helps the fudge set firm as it cooks.
- Chocolate
- Adds chocolate flavour and richness to the fudge.
- Milk
- Supplies moisture and milk solids that give the fudge a softer, creamier texture.
- Butter
- Adds fat for smoothness and a rich mouthfeel.
- Shredded coconut
- Adds chewy texture and a coconut flavour to the fudge.
The step that matters
Boiling until it hardens in cold water. The sugar concentration rises as water boils off, and the fudge sets firmly as it cools. Removing it too early leaves it soft, while cooking too long makes it grainy or hard. Stirring prevents scorching on the bottom of the pan.
Swap the coconut
How well each one fits the dish's main ingredients (sugar, chocolate, milk, butter):
- Vanillafits better
- Coconutthe original
- Figfits less well
- Peachfits less well
Fit is the average pairing score against sugar, chocolate, milk, butter. Candidates are from the same food group and used in at least 100 recipes.
