Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Homemade ketchup
- Provides tomato flavor, acidity and sweetness that give the popcorn its savory-sweet character.
- Butter
- Adds fat that carries the glaze evenly over the popcorn and gives a rich flavor.
- Granulated sugar
- Sweetens the glaze and helps it caramelize slightly as it bakes and dries.
- Plain popcorn
- Serves as the base that absorbs the glaze and bakes into a crisp texture.
The step that matters
Bake until dry and crisp. Stirring during baking helps the glaze dry evenly and keeps coated pieces from clumping or scorching. Popcorn that is pulled too early stays soft and sticky because the sugar and butter have not set, so bake until the popcorn feels dry and crisp.
