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 ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Granulated sugar
- Sweetens the fudge and, as it cooks and cools, helps it set firm.
- Milk
- Adds liquid and milk solids that give the fudge a creamy texture.
- Butter
- Adds fat that makes the fudge smooth and rich.
- Chocolate
- Adds chocolate flavour and richness.
The step that matters
Cooking until the mixture hardens in cold water. The amount of sugar dissolved in the liquid as it cooks decides how firmly the fudge sets. Undercooked fudge stays soft and runny, while overcooked fudge turns hard and grainy. Constant stirring helps prevent scorching on the bottom of the pan.
