Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Mushrooms
- Form the main filling and release moisture and savory flavor as they cook down in butter.
- Butter
- Carries the cooking of the mushrooms and adds richness to the filling and crust.
- Flour
- Thickens the mixture slightly as it cooks, giving the filling body.
- Cream or milk
- Adds moisture and richness, producing a smoother, creamier filling.
The step that matters
Stirring in the cream or milk. Pouring the liquid in gradually while the mixture is warm helps it blend smoothly without lumps. Adding it all at once can trap flour in clumps, and the filling may not thicken evenly.
