Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Rump of beef
- Slow simmering breaks down connective tissue, leaving the meat tender and moist.
- Rice flour
- Starch swells in the hot liquid to thicken the stew into a smooth gravy.
- Mushroom ketchup
- Adds deep savoury, umami flavour that rounds out the gravy.
- Lemon rind
- Lemon oil from the zest adds bright aroma that lifts the rich beef.
- Soy sauce
- Adds salty, savoury depth that supports the meaty flavour.
The step that matters
Thickening the gravy. Rice flour must be mixed smooth with the condiments before going into the pot, otherwise it clumps. Starch only thickens fully once it is heated and simmered, so the gravy needs the full 15 minutes to reach its final body.
Swap the lemon
How well each one fits the dish's main ingredients (beef, pepper, rice, flour, mushroom, ketchup, sauce):

- Coconutfits less well
Fit is the average pairing score against beef, pepper, rice, flour, mushroom, ketchup, sauce. Candidates are from the same food group and used in at least 100 recipes.
