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 Fudge
Ingredients
Directions
Cook the base
In a saucepan, combine brown sugar, milk, chocolate, butter, and vanilla.
Boil the mixture, stirring constantly, until it forms a ball in cold water.
Beat and set
Remove from heat and beat the mixture until it thickens.
Pour into well-greased pans and cut into small squares before it hardens.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Brown sugar
- Adds sweetness and, as it cooks, helps form the fudge's firm, smooth texture.
- Milk
- Provides moisture and creaminess, dissolving the sugar into a smooth mixture.
- Chocolate
- Gives the fudge its chocolate flavour and rich, dense body.
- Butter
- Adds fat that makes the fudge tender and smooth on the palate.
The step that matters
Boil to the ball stage. Sugar must reach the right concentration to set properly. Stopping too early leaves the fudge soft and runny, while cooking too long makes it hard and grainy. Stirring keeps the sugar from crystallising unevenly.
