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 tender texture in the chowder.
- Potatoes
- Add body and starch that soften into the broth, thickening it slightly.
- Milk
- Forms the creamy liquid base that carries the other ingredients.
- Salt pork
- Renders fat that browns and adds savory depth to the base.
- Grated crackers
- Absorb liquid and thicken the chowder while adding a toasty note.
The step that matters
Once boiling, add the clams and cook for a few more minutes.. Clams cook quickly, and overcooking makes them tough and rubbery. Adding them once the milk is boiling and then cooking only briefly keeps them tender. Milk can also scorch or curdle if it is held at a hard boil for too long, so watch the heat.
Swap the onion
How well each one fits the dish's main ingredients (clam, potato, pork, milk, pepper):
