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
In a saucepan, combine sugar, sweet milk, and butter.
Cook over medium heat until the mixture can be rolled into a soft ball when dropped in water.
Remove from heat and stir in vanilla.
Beat the mixture briskly until it thickens.
Pour onto a buttered dish to cool.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Granulated sugar
- Provides sweetness and, as it dissolves and cooks, builds the body of the fudge.
- Sweet milk
- Supplies liquid and milk solids that give the fudge a creamy, soft texture.
- Butter
- Adds fat for a smooth, tender texture and rich flavor.
- Baker's chocolate
- Adds chocolate flavor and color to the fudge.
The step that matters
Cooking to the soft-ball stage. Sugar concentration determines the final texture. Cooking too little leaves the fudge soft and runny; cooking too long makes it hard and grainy. Testing by dropping a little into water shows when it is ready.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
