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

What each ingredient does

Tomatoes
Provide the main body and moisture that cooks down into a spreadable butter.
Apples
Add pectin and body, helping the butter thicken as it cooks.
Sugar
Adds sweetness and, as it concentrates, helps the butter set thicker.
Ground cloves
Add a warm, pungent aroma that defines the spiced flavour.
Cinnamon
Adds a sweet, warm aroma that rounds out the spices.

The step that matters

Stir well and cook until thickened. Thick fruit mixtures scorch easily on the base of the kettle, so constant stirring prevents burning. Cooking until thickened lets water evaporate, concentrating the sugar and fruit pectin until the butter sets to a spreadable consistency.

Swap the tomato

How well each one fits the dish's main ingredients (apple, sugar, clove, cinnamon):

  1. Sweet potatofits better
  2. Parsnipfits better
  3. Capsicumfits better
  4. Tomatothe original

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