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 ↓
After-dinner Mints
Ingredients
Directions
Make the syrup
Combine 10 lbs of sugar, 1 teaspoon of cream of tartar, and 3 quarts of water in a kettle. Heat and mix until boiling.
Remove the paddle and wash the sides of the kettle with a damp brush. Cover and steam for a few minutes.
Remove the cover, insert a thermometer, and cook until the mixture reaches 276 °F.
Pull and shape
Pour the mixture onto a greased slab. Do not turn the edges up until it has set for a few minutes.
Knead the mixture until it is almost cold, then pull it while adding peppermint extract until it is white.
Place 1 lb of fondant on the mixture and continue to pull until well combined.
On a powdered‑sugar‑dusted table, pull the mixture into strips as long as your butter‑cup cutter and about as thick as your finger.
Cut and set
Once the entire batch is pulled, cut it into pieces. Allow to set overnight.
The next morning, the mints should be grained and ready for storage. Optionally, flavor some with lemon, orange, or lime.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Sugar
- Forms the sugar syrup that sets into the firm, crisp body of the mint.
- Cream of tartar
- Acid that helps prevent large sugar crystals, keeping the texture smooth and fine.
- Fondant
- Adds sugar crystals that seed graining, giving the mints their soft, opaque, white texture.
- Water
- Dissolves the sugar so it can be cooked evenly into syrup.
The step that matters
Cooking to 276 °F. Sugar syrup must reach the right temperature to set firm after pulling. Too little cooking leaves the mints soft and sticky, while too much makes them hard and brittle.
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.
