Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Mushrooms
- Provide the main body and earthy flavour of the soup.
- Wheatmeal
- Thickens the soup as it heats, giving it body.
- Butter
- Carries flavour and helps the vegetables brown as they sauté.
The step that matters
Mix the wheatmeal smoothed with milk into the soup. Starch clumps into lumps if added dry or unblended. Smoothing it in a little cold milk first lets the grains separate, so the soup thickens evenly as it heats.
Swap the onion
How well each one fits the dish's main ingredients (mushroom, pepper, butter, milk):
- Capsicumfits better
- Potatofits better
- Tomatofits better
- Onionthe original
Fit is the average pairing score against mushroom, pepper, butter, milk. Candidates are from the same food group and used in at least 100 recipes.
