Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Sirloin or rump steak
- Forms the main body of the dish, cooked to tenderness over high heat.
- Clarified butter
- Coats the steaks and carries heat evenly, helping them brown without burning.
- Fresh butter
- Provides richness and a moist base under the steaks in the serving dish.
- Lemon
- Adds acidity that brightens the rich butter.
- Fried potatoes
- Add crisp, browned texture alongside the tender meat.
The step that matters
Cook the steaks over a clear, brisk fire until done. High, steady heat sears the surface quickly, building browning and flavour while the interior stays juicy. Thin slices overcook fast, so watching closely prevents dryness.
