Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Brown sugar
Provides sweetness and the caramel flavour, and helps the filling thicken as it cooks.
Butter
Adds fat for richness and a smooth, glossy texture in the finished filling.
Cream
Supplies liquid and fat that cook down into a thick, spreadable filling.

The step that matters

Cook until thickened. Boiling sugar and cream concentrates the mixture as water evaporates and the sugar caramelises. Stopping too early leaves it runny, while cooking too long can make it stiff or grainy once cooled.
