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 ↓
Coffee Caramels
Ingredients
Directions
Make the caramel
In a pan, combine sugar and water.
Melt slowly, then boil until it reaches 260°F (127°C).
Add milk and butter, then reboil until a drop in cold water snaps.
Shortly before it is done, add enough cafolin essence to color and flavor.
Set and wrap
Pour into a greased tin and mark into squares when slightly firm.
Once hard, break or cut into pieces and wrap each in waxed paper.

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

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 cooked, the caramel that sets firm.
- Milk
- Adds creaminess and softness and contributes to browning as the mixture cooks.
- Butter
- Adds fat for a rich, smooth texture in the finished caramel.
- Glucose
- Inhibits sugar crystallization, keeping the caramel smooth rather than grainy.
The step that matters
Reboiling after adding milk and butter. Milk proteins and fats can scorch on the pan bottom at high heat, and the mixture can boil over. Stirring and watching the cold-water test keeps the caramel from overcooking or turning bitter.
