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 and crunchy structure that the syrup binds together.
- New orleans molasses
- Adds deep sweetness and flavour, and sets chewy as the syrup cools.
- Light brown sugar
- Adds sweetness and moisture, and helps the balls hold together.
- Vinegar
- Adds acidity that softens the syrup's texture and reacts with the baking soda.
- Baking soda
- Reacts with the acid to release gas, lightening the syrup and making it tender.
- Butter
- Adds richness and a softer bite, and helps the syrup release from the hands.
The step that matters
Add baking soda 5 minutes before removing from heat. Baking soda reacts vigorously with the acid in the syrup, foaming it up. Adding it near the end of cooking lets the reaction lighten the syrup without overcooking it, so the balls stay tender. Shape the balls promptly while the mixture is still warm and workable.
