Use Mushroom Stalks As Stock, Don’t Throw Them Away
You can reduce food waste by combining ingredients in multiple meals – for example, using mushroom stems for broth after using lids in another dish.
Lindsay-Jean Hard of Food52 suggests using shiitake stalks to get the same umami flavor as if you were using whole shiitake mushrooms . When the stems give the broth their flavor, remove them. Once you’ve got your broth, you can use it for anything from the base for mushroom soup to the flavor of just about any sauce.
