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 ↓
Fudge
Ingredients
Directions
Prepare
Heat the milk in a saucepan.
Grate the chocolate and mix it with the sugar in a bowl.
Pour the heated milk over the sugar and chocolate mixture, then add butter.
Cook and finish
Cook until it begins to grain; test by stirring a little in a saucer.
Add 1 cup of either coconut or chopped nuts and 2 teaspoons of vanilla.
Remove from heat and beat well.
Pour into a buttered tin and let it cool slightly before cutting into squares.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Sugar
- Provides sweetness and, as it cooks, forms the fine crystals that give fudge its texture.
- Milk
- Adds moisture and dissolves the sugar, shaping the soft, creamy body of the fudge.
- Chocolate
- Supplies the chocolate flavour and some fat that contributes to a smooth set.
- Butter
- Adds fat for richness and a smoother, more tender texture.
The step that matters
Cook until it begins to grain. Cooking the sugar syrup to the right point sets the crystal size. Stop too early and the fudge stays soft; go too far and it turns hard or sandy. Beating after removing from heat encourages fine, smooth crystals.
