Why it works: Cream and butter 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 ↓
Everton Toffee
Ingredients
Directions
Make the syrup
Combine sugar, water, and cream of tartar in a saucepan.
Heat over medium, stirring occasionally until it boils.
Cover and boil for 10 minutes, then remove the cover.
Finish the toffee
Test the sugar by dropping it into cold water; it should crunch without sticking.
Add melted butter and lemon essence, then boil for a few minutes until combined.
Remove from heat.
Aerate and set
Pour the syrup from a height of 2 feet back into the pan 15-20 times until opaque and creamy.
Pour onto an oiled slab or buttered platter and mark into bars when nearly cool.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Light colored sugar
- Forms the sweet, crisp candy base as the syrup cooks down.
- Best butter
- Adds fat and richness, giving the toffee a softer, smoother bite.
- Cream of tartar
- Adds acidity that helps keep the sugar from crystallising into grainy crystals.
The step that matters
Testing the sugar in cold water. Sugar sets according to how far its water has boiled off. Too little cooking leaves the toffee soft and sticky, while too much makes it hard, bitter, or burnt. The cold-water test shows when it is ready to add butter.
Swap the lemon
How well each one fits the dish's main ingredients (sugar, cream, butter):

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