Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Fish
- Forms the main body of the chowder and provides its flavour.
- Pork
- Fried first to add savoury fat and flavour to the base.
- Potatoes
- Add body and starch that thicken the chowder as they cook.
- Flour
- Cooked with the onions to thicken the broth into a smoother texture.
- Milk
- Adds creaminess and richness to the finished chowder.
- Crackers or biscuits
- Soaked in milk and added to soften and thicken the chowder.
The step that matters
Cooking the flour. Flour must be cooked for several minutes with the onions and fat so its raw starch swells and thickens smoothly rather than tasting pasty or forming lumps. Stirring often keeps it from scorching and sticking.
Swap the onion
How well each one fits the dish's main ingredients (fish, pork, potato, milk, flour, biscuit, pepper):
- Capsicumfits better
