Why it works: Sugar and butter are a kitchen classic. They rank in the top 17% of all ingredient pairs, and cooks put them together in 98,233 recipes. Both carry guaiacol, which smells smoky, sweet. The science ↓
Everton Toffee
Ingredients
Directions
Prepare
Grease a large, shallow dish with butter.
Make the toffee
In a large saucepan, melt the butter over medium heat, coating the bottom well.
Add the treacle and sugar, stirring gently with a knife.
Boil the mixture for about 10 minutes.
To test if it's done, drop a little into a basin of cold water; it should be crisp when cooled.
Set and serve
Pour the toffee mixture into the dish and let it cool until set.

What each ingredient does
- Treacle
- Adds deep flavour and moisture, and helps keep the toffee chewy rather than grainy.
- Sugar
- Provides sweetness and, once boiled, hardens as it cools to set the toffee.
- Butter
- Adds richness and fat, giving the toffee a smooth texture and flavour.
The step that matters
Testing for doneness in cold water. Sugar syrup must reach the right concentration to set firm. Undercooked toffee stays soft and sticky, while overcooked toffee turns brittle or burnt, so the cold-water test helps judge when it is ready.
