Peel and dice the potatoes and onion.
Make the chowder
In a pot, melt the butter and sauté the onion until translucent.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Haddock
- Forms the main body of the chowder and becomes flaky as it cooks.
- Potatoes
- Add body and starch that helps the chowder feel hearty.
- Butter
- Adds richness and carries flavor when the onion is sautéed.
- Milk
- Creates the creamy base of the chowder.
- Flour
- Thickens the liquid so the chowder becomes creamy rather than watery.
- Bread crumbs
- Further thicken the chowder as they absorb liquid.
The step that matters
Adding the flour to the milk and tomatoes. Flour thickens best when it is evenly dispersed in liquid; added in clumps it stays lumpy. Stirring well as it is added, and letting it simmer, lets the starch swell fully and gives a smooth, thickened chowder.
Swap the tomato
How well each one fits the dish's main ingredients (haddock, potato, onion, butter, milk, flour, bread):
- Chivefits better
- Leekfits better
- Shallotfits about as well
- Tomatothe original
Fit is the average pairing score against haddock, potato, onion, butter, milk, flour, bread. Candidates are from the same food group and used in at least 100 recipes.
