Why it works: Syrup and sugar match in chemistry and in kitchens. They rank in the top 6% of all ingredient pairs, and cooks put them together in 5,842 recipes. Both carry ethanol, which smells alcoholic, ethereal. The science ↓
Eyerton Toffee
Ingredients
Directions
Make the toffee
In a large saucepan, melt the butter over medium heat, coating the bottom of the pan.
Add the treacle and sugar, stirring gently with a knife.
Boil for about 10 minutes.
To test, drop a little mixture into a basin of cold water; it should be crisp.
If not brittle, continue boiling for a little longer.
Set and cut
Thoroughly butter or oil a large shallow dish and pour the toffee into it.
When it begins to set, mark it into squares for easier cutting once cold.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Treacle or golden syrup
- Provides the sweetness and deep flavour, and keeps the toffee soft and chewy rather than grainy.
- Moist sugar
- Adds sweetness and molasses-like flavour while helping the toffee set firm as it cools.
- Butter
- Adds richness and fat, giving the toffee a smooth texture and a softer bite.
The step that matters
Boiling to the crisp stage. Sugar syrup sets according to how much water has boiled off. Undercooked toffee stays sticky, while overcooked toffee turns hard and bitter. The cold-water test shows when it has reached a brittle set.
