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 ↓

Ingredients
Directions
The book gives no oven temperature. The 310°F (154°C) in the steps was added when the recipe was transcribed, as a starting point.
Make the toffee
In a common iron saucepan, combine sugar, water, and cream of tartar.
Heat the mixture, stirring occasionally, until it boils.
Cover the saucepan and let it boil for 10 minutes.
Remove the cover and insert a thermometer, boiling until it reaches 310°F (154°C).
If you don't have a thermometer, test the sugar by dipping a clay pipe stem into cold water, then into the boiling sugar, and back into the cold water; it’s done when it slips off easily and crunches without sticking to your teeth.
Once the sugar is ready, pour in the melted butter and essence of lemon.
Allow it to boil for a few minutes until the butter is well mixed in.
Set and cut
Pour the toffee into oiled tin frames or plates.
When nearly cool, mark it into bars with a knife.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Sugar
- Forms the brittle, crisp toffee base and provides sweetness as it cooks to a hard candy stage.
- Cream of tartar
- Acidifies the syrup, helping prevent sugar crystals from forming and keeping the toffee smooth.
- Good butter
- Adds richness and fat, giving the toffee a tender bite and rounded flavour.
The step that matters
Boiling to the target temperature. Sugar syrup must reach about 310°F (154°C) to set into brittle toffee. Stopping early leaves it soft and sticky, while overcooking makes it bitter and burnt. Watching the temperature closely matters.
Swap the lemon
How well each one fits the dish's main ingredients (sugar, cream, butter):

- Strawberryfits better
- Coconutfits better
- 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.
