Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Brown sugar
- Forms the caramel base, providing sweetness and deep flavour as it cooks.
- Cream
- Adds fat and moisture to the caramel, giving it a smooth, soft texture.
- Butter
- Adds richness and fat, softening the caramel and enriching the cake crumb.
- Eggs
- Provide structure and richness to the cake batter when creamed with butter.
- Baking powder
- Releases gas in the batter, helping the cake rise and turn light.
The step that matters
Cook until it reaches a candy stage. Sugar cooked to the candy stage has a precise concentration and temperature. Undercooked caramel stays runny and fails to set, while overcooked caramel turns bitter and burnt. Watch the change closely as the sugar darkens.
