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 ↓
Caramel Fudge
Ingredients
Directions
Make the fudge
In a saucepan, bring sugar and milk to a boil.
Add the caramelized sugar and cook until it reaches the soft ball stage.
Just before removing from heat, add the butter.
Beat and set
Cool undisturbed, then beat vigorously until the mixture loses its glossy appearance.
Pour immediately into a buttered pan and mark into squares.

Sugar and milk barely smell alike, yet cooks put them together in 77,875 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Sugar
- Forms the sweet base and, when caramelized, adds deep toffee flavour.
- Milk
- Adds moisture and dairy richness, helping create a soft, creamy texture.
- Butter
- Adds fat for smoothness and a rich mouthfeel in the finished fudge.
The step that matters
Beating after cooling. Beating the mixture while it cools encourages fine sugar crystals to form, giving fudge its smooth, creamy texture. Beating too early or too late can leave it grainy or too stiff to shape.
