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 ↓

Ingredients
Directions
Make the fudge

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Sugar
- Dissolves and sets into the firm, sweet body of the fudge as it cooks.
- Milk
- Adds moisture and dissolves the sugar, giving the fudge a creamy texture.
- Chocolate
- Provides the chocolate flavour and fat that help make the fudge smooth.
- Butter
- Adds fat for richness and a smoother, less grainy texture.
The step that matters
Cooking to the soft-ball stage. Stopping too early leaves the fudge soft and runny, while cooking too long makes it hard and crumbly. Stirring constantly prevents sugar from scorching or crystallising unevenly on the bottom of the pan.
Swap the walnut
How well each one fits the dish's main ingredients (sugar, milk, chocolate, butter):
- Almondfits better
- Cocoafits better
- Pecansfits better
- Walnutthe original
Fit is the average pairing score against sugar, milk, chocolate, butter. Candidates are from the same food group and used in at least 100 recipes.
