Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Potatoes: Break down during cooking to give the soup body and a thick, creamy texture.
Flour: Thickens the milk into a smooth, creamy base as it cooks.
Milk: Forms the liquid base that the flour thickens into a creamy soup.
Ham: Adds savory, salty meaty flavor to the soup.
Blue cheese: Adds sharp, tangy flavor that contrasts with the creamy base.
Frozen peas: Add sweetness and a bright green color, and soften as they cook.

The step that matters

Slowly add milk and cook until thickened. Adding milk gradually while stirring keeps the flour smooth and prevents lumps. Cooking until thickened lets the starch swell fully, which sets the soup's body.

Fit is the average pairing score against butter, onion, potato, flour, milk, peas, ham. 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).
