Ingredients
Directions
Prepare
Remove the stems from the mushrooms and peel them.
Make the mushroom sauce
Melt the butter in a saucepan over low heat.
Add the mushrooms, mace, and cayenne; stew for 10 to 15 minutes, stirring often.

Gradually pour in the gravy or broth and simmer for 2 minutes.
Season with salt and lemon juice.
Serve
Pour the mixture onto a thick slice of bread that has been hollowed out and fried in butter until light brown.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Mushrooms
- Main body of the topping, releasing moisture and savoury flavour as they stew.
- Butter
- Fat that cooks the mushrooms and fries the bread, adding richness and browning.
- Flour
- Thickens the cooking liquid into a sauce once it is browned in the butter.
- Gravy or beef broth
- Liquid that forms the body of the sauce and adds savoury meaty flavour.
- Bread
- Crisp fried base that holds the mushroom mixture.
The step that matters
Stirring the flour until lightly browned. Flour must cook in the butter long enough to lose its raw taste and to thicken smoothly; if the liquid is added too early or too cold, lumps form and the sauce stays floury.
Swap the mace
How well each one fits the dish's main ingredients (mushroom, butter, pepper, flour, beef, lemon, bread):
- Thymefits better
- Parsleyfits better
- Marjoramfits better
- Macethe original
Fit is the average pairing score against mushroom, butter, pepper, flour, beef, lemon, bread. Candidates are from the same food group and used in at least 100 recipes.
