Ingredients
Directions
Prepare and simmer
Remove the skin and fat from the beef and cut it into 2-inch square pieces.
Pour the cold broth or gravy over the beef and bring it to a boil.
Add salt and cayenne pepper to taste, then reduce to a simmer for 2 hours.
After 2 hours, add the grated lemon rind.
Thicken and finish

Stir the mixture into the stew.
Cook for an additional 15 minutes before serving.

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 main meat, which becomes tender through long, slow simmering.
- Rice flour
- Thickens the cooking liquid into a smooth, lightly body-filled stew.
- Mushroom ketchup
- Adds deep savoury, umami flavour to the broth.
- Lemon rind
- Adds bright aromatic citrus oil that lifts the rich beef flavour.
The step that matters
Stirring in the rice flour mixture. Flour clumps if added dry or without being mixed smoothly with liquid first. Blending it with the ketchup and lemon juice before adding it to the hot stew lets the starch disperse and thicken evenly.
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.
