Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Gourds
- Form the main body of the soup and give it its bulk and mild flavor.
- Onions
- Add savory sweetness and aroma as they soften in the butter.
- Butter
- Carries the aromatics and adds richness as it cooks the vegetables gently.
- Crust of bread
- Thickens the soup slightly and gives it body.
- Consommé
- Supplies the liquid base and savory depth of the soup.
The step that matters
Cook the gourds and onions until tender without browning. Over low heat the vegetables soften and release their sweetness; if they scorch, bitter burnt flavors enter the soup and cannot be removed by straining.
Swap the onion
How well each one fits the dish's main ingredients (butter, bread, pepper):

- Potatofits about as well
- Onionthe original
Fit is the average pairing score against butter, bread, pepper. Candidates are from the same food group and used in at least 100 recipes.
