Why it works: Butter and lemon are a kitchen classic. They rank in the top 16% of all ingredient pairs, and cooks put them together in 41,227 recipes. Both carry 3-hexenal, which smells apple, fruity. The science ↓

Sugar and lemon barely smell alike, yet cooks put them together in 53,532 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
- Powdered loaf sugar
- Dissolves in the water to form a syrup that cooks down into the toffee's sweet, brittle body.
- Butter
- Adds fat and richness, giving the toffee a smooth texture and a softer bite.
The step that matters
Stirring until a small amount sets when poured. Toffee hardens as its sugar concentration rises and its temperature climbs. Stopping too early leaves it soft and sticky, while cooking too long can make it burnt or overly brittle.

Fit is the average pairing score against sugar, butter. Candidates are from the same food group and used in at least 100 recipes.
