Ingredients
Directions
Prepare
Fry the salt pork in a pan until brown, then remove it.
Add the sliced onions to the pan and fry for about 10 minutes, stirring constantly.
Layer and smother
Leave a thin layer of onions in the pan, then place the slice of steak on top.
Add a layer of onions, then another slice of steak, and cover thickly with onions.
Dredge each layer with pepper, salt, and flour.

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 meat, cooking gently under the onion layers to stay tender and juicy.
- Onions
- Soften and sweeten as they fry, forming a moist, savoury blanket over the steak.
- Salt pork
- Renders fat into the pan, adding richness and flavour for frying the onions.
- Flour
- Dusted between layers, it thickens the cooking juices into a light sauce.
The step that matters
Frying the onions for about 10 minutes while stirring constantly. Onions that are not stirred can scorch on the pan base before they soften and turn sweet. Constant stirring spreads heat evenly so they cook down gently and brown without burning.
