Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Onions
- Soften and sweeten as they fry, adding savoury flavour and a soft topping for the steak.
- Butter
- Adds richness and carries flavour when frying the onions and dressing the steak.
- Beef steak
- Provides the main protein; cooked first, then served topped with the onions.
