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

What each ingredient does

Granulated sugar
Forms the sweet base that sets firm as the syrup cooks and cools.
Corn syrup
Keeps the sugar from crystallizing, giving the candy a smooth texture.
Egg whites
Whipped into foam, they give the fudge its light, airy structure.

The step that matters

Boiling the syrup to the hard-ball stage. Sugar syrup sets according to its final temperature. Boiling it until it hardens in cold water concentrates the sugar enough for the candy to set firm rather than soft or sticky.
