Mushroom Sauce

Ingredients

Directions

  1. Put the beef gravy into a saucepan and thicken it with the butter and flour over medium heat until it bubbles.

  2. Prepare the mushrooms by cutting off the stalks and wiping them clean of grit and dirt.

  3. If using large mushrooms, cut them into small pieces.

  4. Add the mushrooms to the gravy and let them simmer gently for about 10 minutes.

  5. Stir in the mushroom ketchup and serve.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Button mushrooms
Provide the main earthy flavor and body, softening and blending into the sauce as they simmer.
Beef gravy
Forms the savory liquid base of the sauce.
Mushroom ketchup
Adds concentrated savory depth and a hint of tang.
Butter
Adds richness and works with the flour to thicken the gravy.
Flour
Its starch thickens the gravy, giving the sauce body.

The step that matters

Thicken the gravy until it bubbles. Heating the butter and flour into the gravy until it bubbles lets the flour's starch swell and thicken the sauce. Stopping early leaves the sauce thin and can leave a raw floury taste.
