Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Rump of beef
- Provides the meat that becomes tender during long, slow simmering.
- Rice flour
- Thickens the cooking liquid into a light, glossy stew body.
- Mushroom ketchup
- Adds savoury, umami depth to the broth and gravy.
- Lemon rind
- Contributes bright aroma and citrus flavour to the stew.
The step that matters
Stirring in the rice flour mixture. Flour mixed with liquid first disperses evenly, so it thickens smoothly; added dry or in lumps it forms clumps that stay raw-tasting and grainy. Simmering after adding it cooks out the starchy taste.
Swap the lemon
How well each one fits the dish's main ingredients (beef, pepper, rice, flour, mushroom, ketchup, white wine):
- Lemonthe original
- Limefits about as well
- Grapefits less well
- Avocadofits less well
Fit is the average pairing score against beef, pepper, rice, flour, mushroom, ketchup, white wine. Candidates are from the same food group and used in at least 100 recipes.
