Why it works: Butter and cream are a kitchen classic. They rank in the top 8% of all ingredient pairs, and cooks put them together in 41,516 recipes. Both carry delta-dodecalactone, which smells sweet, creamy. The science ↓
Ice Cream Candy
Ingredients
Directions
Make the candy
Boil water, sugar, butter, cream of tartar, and vanilla until thick and hard.
Test the mixture by dipping your finger into it and then into cold water; it should crack like glass when done.
Pour the mixture onto a marble slab to cool.
Pull and cut
Once cool, pull the candy over a large hook until it becomes porous.
Cut into sticks for use.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Sugar
- Forms the sweet body of the candy and hardens into a brittle structure as it cooks.
- Cream of tartar
- Acidifies the syrup, helping prevent crystallization so the candy stays smooth.
- Unsalted butter
- Adds fat for richness and a tender bite in the finished candy.
The step that matters
Testing the mixture in cold water. Sugar syrup changes quickly near the final stage, so the cold-water test shows when it has cooked enough to set hard. Undercooked syrup stays sticky, while overcooked syrup turns bitter and brittle.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
