Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Beef
- Provides the main protein, which becomes tender with slow cooking.
- Flour
- Thickens the cooking liquid into a gravy.
- Tomatoes
- Add acidity and liquid that builds the savoury gravy base.
- Butter or fat
- Carries the heat for browning the beef, adding flavour to the surface.
- Mushrooms
- Add earthy flavour and body to the gravy.
The step that matters
Brown the beef in butter or fat. Browning the meat's surface triggers the Maillard reaction, which creates deep savoury flavour that carries into the gravy. Pale, steamed meat gives a flat result.
Swap the tomato
