Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Popped corn
- Forms the bulk that the syrup coats and holds together into balls.
- New orleans molasses
- Adds deep sweetness, dark flavor, and moisture that keeps the syrup sticky.
- Light brown sugar
- Adds sweetness and helps the syrup set chewy as it cools.
- Vinegar
- Adds acidity that balances the sweetness and reacts with the baking soda.
- Butter
- Adds fat that softens the texture and helps the syrup coat the corn.
- Baking soda
- Reacts with the acid to foam the syrup, lightening its texture.
The step that matters
Add baking soda 5 minutes before done. Baking soda reacts with the acid in the vinegar and foams the hot syrup, which lightens the texture. Adding it at the right point, then mixing quickly, keeps the foam trapped so the balls are light rather than dense or flat.
Swap the walnut
How well each one fits the dish's main ingredients (corn, molasses, sugar, vinegar, butter):
- Beansfits better
- Almondfits better
- Peanutfits about as well
- Walnutthe original
Fit is the average pairing score against corn, molasses, sugar, vinegar, butter. Candidates are from the same food group and used in at least 100 recipes.
