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

What each ingredient does

Apples
Break down into smooth body and natural sweetness for the soup base.
Tomatoes
Provide the main flavor and bulk of the soup base.
Onions
Add savory depth and aroma to the cooked base.
Malt vinegar
Adds acidity that brightens the soup's flavor.
Mustard
Adds pungent flavor that complements the acidity and sweetness.

The step that matters

Strain the mixture through a sieve. Cooked apples, tomatoes, and onions must be broken down fully before straining; under-cooked pieces stay coarse and leave the soup grainy rather than smooth.
