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

What each ingredient does

Granulated sugar
Provides sweetness and, as it cooks to the soft ball stage, the firm structure that sets the filling.
Cream
Adds moisture and a smooth, rich texture to the filling.
Chocolate
Supplies the main flavor and, as it cools, helps the filling thicken and set.
Butter
Adds fat for a smoother, silkier mouthfeel and a glossy finish.

The step that matters

Do not stir after it begins to boil. Stirring a sugar syrup once it boils can encourage sugar crystals to form, which leaves the filling grainy instead of smooth. Letting it cook undisturbed keeps the texture even.
