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 ↓
Lime Juice Drops
Ingredients
Directions
Make the syrup
Cook sugar and cream of tartar (or glucose) until just before it turns yellow, washing down the sides of the basin.
Pour the mixture onto an oiled or greased slab.
Flavor and shape
Form tartaric acid into a paste with a few drops of lime juice and work it into the batch.
Add green food coloring and oil of lime, mixing well.
Run the mixture through a drop machine to form thin round or square drops.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Sugar
- Forms the hard, glassy body of the drops as it cooks.
- Cream of tartar
- Helps prevent crystallization, keeping the candy smooth and clear.
- Tartaric acid
- Adds a sharp, sour bite that balances the sweetness.
- Glucose
- Replaces cream of tartar as an interfering agent, keeping the candy smooth and clear.
The step that matters
Cooking the sugar syrup. Cooking to just before yellow matters because pushing the sugar further starts caramelization, which adds color and a burnt flavor that clashes with the bright lime taste.
Swap the lime

Fit is the average pairing score against sugar, cream. Candidates are from the same food group and used in at least 100 recipes.
