Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Salt pork
- Renders fat that flavours the frying onion and the whole chowder base.
- Flour
- Thickens the milk and broth into a creamy, body-rich chowder.
- Potatoes
- Soften during cooking and give the chowder its body and bulk.
- Milk
- Adds creaminess and richness to the broth.
- Fish
- Provides the main protein and flavour of the chowder.
The step that matters
Stirring in the flour mixture. Flour thickens only when heated in liquid and stirred, so lumps can form if it is added cold or not dispersed first. Mixing it with cold milk before adding it to the pot helps it blend smoothly as the chowder thickens.
Swap the onion
