Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Hens
- Release flavour and body into the broth as they simmer.
- Ham hock
- Adds smoky, savoury depth to the broth.
- Washed rice
- Absorbs liquid and softens, thickening the soup slightly.
- Flour
- Thickens the soup when stirred in with butter.
- Butter
- Adds richness and helps flour blend smoothly into the soup.
The step that matters
Stirring in the flour and butter. Flour added directly to hot liquid clumps. Mixing it with butter first coats the particles so they disperse evenly and thicken the soup smoothly.
Swap the tomato
The recipe marks tomato as optional. How well each one fits the dish's main ingredients (ham, rice, corn, thyme, flour, butter):
- Okrafits better
- Shallotfits better
- Leekfits better
- Tomatothe original
