What kind of mushroom do you need for mushroom sauce?
Wine, broth or cream might form the base for this versatile topping. Aromatics, such as garlic or fresh herbs, often add their own flavor dimension. A thickened sauce might use flour or arrowroot or, for a quick-cooked version, canned cream soup. Mushroom sauce pairs well with most proteins, including beef, poultry or fish, and it nicely complements vegetables, such as asparagus and broccoli. Source: allrecipes.com
