Why it works: Apple and cinnamon are a kitchen classic. They rank in the top 4% of all ingredient pairs, and cooks put them together in 5,598 recipes. Both carry methyl cinnamate, which smells strawberry. The science ↓

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.
Swap the tomato
How well each one fits the dish's main ingredients (apple, sugar, cinnamon):
- Sweet potatofits better
- Parsnipfits better
- Capsicumfits better

Fit is the average pairing score against apple, sugar, cinnamon. Candidates are from the same food group and used in at least 100 recipes.
