Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Clams
- Provide the main seafood flavor and body of the chowder.
- Potatoes
- Thicken the broth as they cook and give the chowder its substance.
- Pilot crackers
- Soak up liquid and help thicken the chowder.
- Fat salt pork
- Renders fat that carries flavor into the onions and pot.
- Onions
- Add sweetness and aroma as they soften in the pork fat.
- Tomatoes
- Add acidity and a touch of sweetness to balance the broth.
The step that matters
Boiling the layered pot for 1.5 hours. Boiling too hard can break down the potatoes and crackers unevenly and cloud the broth, while too little time leaves the potatoes firm. Keep a steady simmer-level boil so the starches soften and thicken the chowder evenly.
Swap the onion
How well each one fits the dish's main ingredients (clam, potato, pork, tomato, pepper, parsley):
- Capsicumfits better
- Carrotfits better
- Onionthe original
- Okrafits about as well
Fit is the average pairing score against clam, potato, pork, tomato, pepper, parsley. Candidates are from the same food group and used in at least 100 recipes.
