Ingredients
Directions
In a pot, pour the broth or gravy over the beef and bring to a boil.
Add salt and cayenne pepper as needed, then reduce to a simmer for 2 hours.

Stir the mixture into the stew and 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, gentle simmering.
- Rice flour
- Thickens the stew's liquid as it cooks, giving it body.
- Mushroom ketchup
- Adds deep savoury, umami flavour to the stew.
- Lemon rind
- Adds bright aroma and citrus flavour to the stew.
- Lemon juice
- Adds acidity that brightens the rich, savoury flavours.
The step that matters
Stirring the flour mixture into the stew. Rice flour mixed with liquid can clump if added in lumps. Mixing it smooth first, then stirring it through the hot stew, lets the starch disperse evenly and thicken the liquid without lumps.
Swap the lemon
How well each one fits the dish's main ingredients (beef, pepper, rice, flour, mushroom, ketchup, sauce):
