Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Lentils
- Break down during simmering to thicken the soup and add body.
- Potatoes
- Break down slightly as they cook, adding starch that thickens the soup.
- Milk
- Adds creaminess and softens the flavour of the vegetable broth.
- Red kidney beans
- Add substance and texture, holding their shape after heating through.
- Butter beans
- Add creamy texture and body, holding their shape after heating through.
- Carrots
- Add natural sweetness and colour as they soften in the butter.
The step that matters
Simmer the lentils gently. Simmering too hard can break lentils apart unevenly and scorch the milk on the base of the pan. A gentle simmer keeps the soup smooth and evenly textured.

Fit is the average pairing score against butter, carrot, parsnip, onion, potato, pepper, milk. 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).
