Why it works: Butter and cream are a kitchen classic. They rank in the top 8% of all ingredient pairs, and cooks put them together in 41,516 recipes. Both carry delta-dodecalactone, which smells sweet, creamy. The science ↓
Butter Scotch
Ingredients
Directions
Cook the candy
In a saucepan, combine the coffee and sugar and enough cold water to dissolve it.
Boil the mixture without stirring until it snaps in cold water.
Flavor, pour and mark
Once done, add the lemon extract.
Pour the mixture into well-buttered pans to a thickness of ¼ inch.
When partly cool, mark off into squares.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Coffee a sugar
- Dissolves and cooks into a hard, brittle candy base that gives the sweetness and set.
- Butter
- Greases the pans and adds richness and a smoother, softer bite to the candy.
- Cream of tartar
- Adds mild acidity that helps keep the sugar from crystallizing into a grainy texture.
The step that matters
Boil without stirring until it snaps in cold water. Sugar syrup's final texture depends on how far it cooks. Stirring can trigger sugar crystals that make the candy grainy, so the mixture is left undisturbed and tested in cold water to judge when it has reached the hard, brittle stage.
Swap the lemon
How well each one fits the dish's main ingredients (coffee, sugar, butter, cream):
- Vanillafits better
- Strawberryfits better
- Coconutfits better
- Lemonthe original
Fit is the average pairing score against coffee, sugar, butter, cream. Candidates are from the same food group and used in at least 100 recipes.
