Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Coats the meat so it browns well and helps thicken the gravy.
- Butter
- Fries the meat for browning and, rolled in flour, thickens the stew.
- Brown gravy
- Provides the liquid base and savoury flavour for the stew.
- Onion
- Adds aromatic sweetness and depth as it softens in the stew.
The step that matters
Stew slowly without boiling. Gentle heat keeps the meat tender and lets the flour-thickened sauce become smooth. A hard boil can toughen the meat and cause the sauce to break or stick.
Swap the lemon
The recipe marks lemon as optional. How well each one fits the dish's main ingredients (meat, flour, butter, onion, pepper):
- Avocadofits better
- Limefits about as well
- Coconutfits about as well
- Lemonthe original
Fit is the average pairing score against meat, flour, butter, onion, pepper. Candidates are from the same food group and used in at least 100 recipes.
