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

What each ingredient does

Dark brown sugar
Provides the bulk of the sweetness and the caramel flavor as it cooks.
Butter
Adds fat for a smooth, rich texture and helps keep the filling soft.
Cream or milk
Dissolves the sugar and adds moisture, so the mixture cooks to a creamy, pourable texture.
Vanilla
Adds aroma that rounds out the caramel flavor.

The step that matters

Cooking to the cold-water ball stage. Sugar syrup firms as its temperature rises and water evaporates. Stopping too early leaves the filling runny, while cooking too long makes it hard and grainy when it cools. Testing in cold water shows when it has reached the right concentration.
