Why it works: Cream and butter 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 ↓
Butter Cups
Ingredients
Directions
Cook the sugar
Combine sugar and water in a large pot.
Bring the mixture to a boil.
Add molasses and cream of tartar.
Cook until the mixture reaches 310°F (154°C).
Stir in the butter until fully dissolved.
Pour the mixture onto a greased slab.
Prepare the cream
Work the vanilla cream until smooth.
Warm the vanilla cream over a heater, turning continuously.
Shape the candy
Once the sugar mixture is cool enough to handle, spread it into a sheet about 1 inch thick and 12‑14 inches wide.
Place the warm vanilla cream in a roll at the center of the sugar sheet.
Fold the sugar over the cream, meeting the edges.
Roll the candy before the heater until it is warm enough to work.
Spin out into stick candy.
Mark the sticks with a caramel marker.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Sugar
- Forms the main candy structure and provides most of the sweetness as it sets.
- New orleans molasses
- Adds deeper flavor, color, and some moisture to the sugar mixture.
- Cream of tartar
- Acidifies the syrup, helping prevent unwanted sugar crystallization for a smoother texture.
- Sweet butter
- Adds fat for richness and a softer, more tender bite.
- Vanilla cream
- Forms the soft filling enclosed in the sugar, adding flavor and contrast in texture.
The step that matters
Cooking to 310°F (154°C). Final sugar temperature determines the candy's hardness after cooling. Undercooking leaves it sticky and soft, while overcooking makes it brittle and prone to burning.
“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.
