Mushroom Sauce

Ingredients

Directions

Prepare

  1. Wash the mushrooms and remove the stems and outer skins.

  2. Select mushrooms that are dull pearl on the outside and tinged with pale pink underneath.

  3. For enhanced flavor, salt a few mushrooms the night before to extract their juice.

Make the sauce

  1. Stew the mushrooms slowly in veal gravy, milk, or cream.

  2. Add the chopped onion and season with pepper, salt, and the butter rolled in flour.

  3. If a poisonous mushroom is present, the onion will turn black; discard the sauce if this occurs.

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 body and savory flavor of the sauce.
Veal gravy, milk, or cream
Forms the liquid base that carries the mushrooms and thickens into a sauce.
Butter rolled in flour
Flour and butter form a roux that thickens the sauce and adds richness.
Onion
Adds aromatic sweetness and savory depth to the sauce.

The step that matters

Stewing the mushrooms slowly. Gentle, slow heat draws out the mushrooms' juices and flavor without toughening them or scorching the liquid. Rapid boiling can make the sauce tough and cause it to scorch or break.

Swap the onion

How well each one fits the dish's main ingredients (mushroom, veal, pepper, butter, flour):

  1. Shallotfits better
  2. Capsicumfits better
  3. Spinachfits better
  4. Onionthe original

Fit is the average pairing score against mushroom, veal, pepper, butter, flour. Candidates are from the same food group and used in at least 100 recipes.
