Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Beef steak
- Provides the main protein, which becomes tender as it cooks slowly in its own juices.
- Butter
- Adds fat and richness to the pan, carrying flavour across the steak's surface.
- Onion
- Releases moisture and sweetness as it cooks, flavouring the juices around the steak.
The step that matters
Cook in its own juices. Cooking gently over a long period lets the connective tissue in the steak break down, which keeps it tender. Cooking too hard or too fast can leave the meat tough and dry.
