Why it works: Sugar and molasses 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
Prepare
Combine the slightly salted popped corn in a large dishpan.
In a saucepan, mix sugar, molasses, butter, and vinegar.
Boil the mixture until it forms a ball when dropped into cold water.
Coat and shape
Remove from heat, add baking soda, and stir well.
Pour the mixture over the popped corn and stir with a spoon.
Flour your hands and quickly mold the mixture 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
- Sugar
- Forms the sweet syrup base and hardens as it cools, holding the balls together.
- Molasses
- Adds depth of flavour and moisture, and keeps the coating soft and chewy.
- Baking soda
- Reacts with the acid in the syrup to create gas bubbles, lightening the coating.
- Vinegar
- Acidity helps prevent the sugar from crystallising, keeping the syrup smooth.
The step that matters
Boiling the syrup to the ball stage. Boiling to the correct point controls how much water remains. Too little boiling leaves the coating sticky and soft, while overboiling makes it hard and brittle once cooled.
“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.
