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

What each ingredient does

Sugar
Forms the sweet crystalline body of the candy as it cooks and sets.
Cream
Adds fat and moisture, giving the candy a softer, smoother texture.

The step that matters

Boil until it forms a soft ball when dropped in water. Cooking sugar to the right temperature controls how much water remains and how the sugar crystallizes. Too little cooking leaves the candy soft and sticky; too much makes it hard and brittle.
