Why it works: Molasses and sugar are a kitchen classic. They rank in the top 11% of all ingredient pairs, and cooks put them together in 9,225 recipes. Both carry ethanol, which smells alcoholic, ethereal. The science ↓
Popcorn Balls
Ingredients
Directions
Make the syrup
In a large iron kettle, cook the molasses, vinegar, brown sugar, and baking soda until it reaches the hard crack stage.
Remove from heat and add the baking soda dissolved in 1 tablespoon of hot water.
Add the popcorn and shape
When the mixture begins to rise, quickly stir in the popcorn until well mixed.
Turn the mixture out onto a buttered or oiled platter and shape into balls while still warm.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Molasses
- Provides deep sweetness and flavor, and a chewy texture as the syrup cools.
- Brown sugar
- Adds sweetness and helps the syrup set firm and chewy when cooled.
- Vinegar
- Adds a slight acidity that helps keep the sugar syrup smooth rather than grainy.
- Baking soda
- Reacts with the hot syrup so it foams and rises, lightening the set coating.
- Freshly popped corn
- Forms the bulk of each ball, held together by the syrup coating.
The step that matters
Stir in the popcorn as soon as the mixture begins to rise. Once baking soda reacts with the hot syrup, the mixture foams and begins to set quickly. Adding the popcorn promptly lets it coat evenly before the syrup stiffens.
“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.
