What each ingredient does

Mushrooms: Provide the main savoury body and moisture that becomes the topping, softening as they cook.
Butter: Adds fat and richness, helping the steak and mushrooms brown and carry flavour.
Raw minced steak: Provides the meaty base; pressing it dry lets it brown rather than steam.

The step that matters

Press the meat until dry. Pressing the cooked meat against the pan drives off excess liquid so it can brown instead of steaming. Leftover moisture would dilute the savoury juices the mushrooms cook in.
