Ingredients
Directions
Prepare
Beat the beef steak with a rolling pin.
Fry the sliced onion in dripping until nicely browned.
Boil the macaroni in salted water for 10 minutes.
Soak the brown bread crust in hot water for 10 minutes, then pour the water over the onion and keep warm.
Cook and serve
Sprinkle the steak with salt, pepper, and flour, then fry in a hot pan for 5 minutes on each side.
Remove the steak, pour the onion into the pan, heat it, and add ketchup.
Serve the onion over the steak and arrange the macaroni around it.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Beef steak
- Forms the main protein; frying in a hot pan browns its surface and adds savoury flavour.
- Onion
- Browning in dripping builds sweet, savoury flavour that forms the base of the sauce.
- Macaroni
- Provides starch that makes the plate filling and absorbs the flavours of the dish.
- Brown bread crust
- Soaked in hot water, it adds body and a toasty, roasted flavour to the onion liquid.
- Ketchup
- Adds sweetness and acidity to the onion mixture, rounding out its flavour.
The step that matters
Frying the steak in a hot pan. A very hot pan browns the surface quickly through the Maillard reaction, creating flavour. If the pan is not hot enough, the steak steams, turns grey and tastes flat.
