Ingredients
Directions
Prepare and fry
Prepare the steak for broiling, season with pepper, and roll in flour.
Fry the steak in lard until done, then remove from the pan.
Make the gravy and serve
In the same pan, add the chopped onion, pepper, salt, water, and a little mustard to make gravy.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Steak
- Is the main protein, seared in lard and then simmered in the gravy to finish.
- Flour
- Coats the steak so it browns in the fat and helps thicken the pan gravy.
- Lard
- Fries the steak and carries browning flavour into the pan for the gravy.
- Onion
- Softens and sweetens as it cooks, adding savoury flavour to the gravy.
- Mustard
- Adds a sharp, pungent note that balances the richness of the gravy.
The step that matters
Fry the steak in lard until done, then remove from the pan. Floured meat browns best in hot fat, and the browned bits left in the pan give the gravy its flavour. Removing the steak at the right point keeps it from overcooking when it returns to the gravy.
