Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Pork
- Rendered fat provides flavour for the broth.
- Onions
- Browning them adds sweetness and depth to the broth.
- Potatoes
- Starch from the potatoes adds body and substance to the chowder.
- Fish
- Provides the main protein and flavour of the chowder.
- Flour
- Thickens the liquid so the chowder turns creamy.
- Cream
- Adds richness and a smooth, velvety texture.
The step that matters
Thicken with flour and cream. Flour must be mixed smoothly into the cream before it goes into the hot chowder, or it will clump. Once added, the chowder should be kept gently warm rather than boiled, since boiling can cause the cream to separate.
Swap the onion
