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

What each ingredient does

Tomatoes
Form the bulk of the chowder and break down into its main body and moisture.
Green peppers
Add vegetable body and a fresh, slightly bitter edge that stands up to long cooking.
Onions
Build savory aroma and sweetness as they soften during the long simmer.
Vinegar
Adds sharp acidity that balances the sweetness and helps preserve the chowder.
Sugar
Adds sweetness that rounds out the acidity of the vinegar and tomatoes.
Allspice
Contributes warm, aromatic spice flavour that infuses the chowder during simmering.

The step that matters

Boil the mixture slowly for 2 hours. Simmering gently over a long period lets the tomatoes and peppers break down and the spices infuse evenly. A hard boil can scorch the bottom of the pot and make the chowder taste burnt.
