Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Oysters
- Provide the main flavour and the body of the soup.
- Potatoes
- Add starch and bulk, giving the soup a thicker, heartier texture.
- Butter
- Adds richness and fat, rounding out the broth's flavour and mouthfeel.
- Milk
- Adds creaminess and a mild sweetness to the broth.
- Crackers
- Crushed crackers soak up liquid and help thicken the soup.
The step that matters
Stirring in the oysters once the liquid boils. Oysters overcook quickly and turn rubbery, and milk-based liquids can scorch on the bottom of the pan. Stirring well keeps the oysters tender and the soup from sticking and burning.

- Capsicumabout as good a flavor fit
Fit is the average pairing score against butter, milk, pepper, oyster. 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).
