Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Tomato
Provides the main body and tart, savory base of the butter.
Apple
Adds natural pectin and body, helping the butter thicken as it cooks.
Sugar
Sweetens the butter and helps it thicken into a spreadable, preserve-like texture.

The step that matters

Cooking until it resembles a preserve. Cook slowly and stir often over medium heat so the sugar and fruit concentrate and thicken evenly. Too little cooking leaves it runny, while scorching on the bottom gives a burnt taste.
