Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Oysters
- Provide the main seafood flavor and tender texture in the soup.
- Raw potatoes
- Add body and starch that thickens the broth slightly as they cook.
- Milk
- Forms the creamy, rich base of the soup.
- Cracker crumbs
- Thicken the milk base and add a light body to the soup.
- Butter
- Adds richness and a silky mouthfeel to the finished soup.
The step that matters
Stir the oysters in while the milk is at a boil. Milk scorches easily on the bottom of a pan, and constant stirring spreads heat evenly. Stirring also keeps the dairy from separating and sticking, which would spoil the smooth texture of the soup.
Flavor stand-ins for the potato
How well each one fits the dish's main ingredients (milk, pepper, oyster, egg, butter):

- Asparagusabout as good a flavor fit
Fit is the average pairing score against milk, pepper, oyster, egg, butter. Candidates are from the same food group and used in at least 100 recipes. This compares flavor only: it does not check the job the ingredient does in the dish (bulk, moisture, acidity, structure).
