Why it works: Sugar and cream are a kitchen classic. They rank in the top 9% of all ingredient pairs, and cooks put them together in 43,450 recipes. Both carry 2,3-butanedione, which smells butter, sweet. The science ↓

Ingredients
Directions
Make the syrup
Combine sugar and boiling water in a saucepan.
Stir constantly over low heat until dissolved.
Cover the saucepan and bring to a boil over high heat for about 10 minutes, or until it threads slightly.
Finish and shape
Remove from heat, cool slightly, add peppermint extract, and beat until it forms a soft cream fondant.
Drop spoonfuls onto waxed paper.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Sugar
- Forms the sweet base that cooks into a syrup and then sets into a soft, creamy fondant.
- Cream of tartar
- Acidifies the syrup, helping prevent sugar crystals from forming a grainy texture.
The step that matters
Beating the cooled syrup into fondant. The syrup must cool slightly before beating. Beating while it is too hot yields large sugar crystals, while beating it too cool can make it hard to work. Careful cooling and beating produce a smooth, soft cream.
Swap the peppermint
How well each one fits the dish's main ingredients (sugar, cream):
- Nutmegfits better
- Cinnamonfits better
- Gingerfits about as well
- Peppermintthe original
Fit is the average pairing score against sugar, cream. Candidates are from the same food group and used in at least 100 recipes.
