Why it works: Vinegar and pepper are a kitchen classic. They rank in the top 14% of all ingredient pairs, and cooks put them together in 27,814 recipes. Both carry 4'-methylacetophenone, which smells bitter almond. The science ↓
Treacle Toffee
Ingredients
Directions
Make the toffee
Rub the saucepan with butter and pour in as much treacle as may be wanted.
Let it boil gently until a small portion will break between the teeth after being thrown into cold water.
When this point is reached, take the pan off the fire immediately, or it will quickly acquire a burnt taste.
Flavor, set and shape
Pour the hot mixture onto a buttered dish, and when cool, roll it into sticks and fold in clean white paper.
Add essence of peppermint, almond, or lemon to flavor the toffee.
Add a little cayenne pepper to the toffee.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Treacle (in the method)
- Forms the dark, sweet base of the toffee and sets firm as it cools.
- Butter (in the method)
- Greases the pan and dish so the hot toffee does not stick.
The step that matters
Take the pan off the fire at the right moment. Treacle keeps darkening and then scorches quickly once it reaches the hard-crack stage, so removing it from the heat as soon as the cold-water test passes prevents a burnt taste.
