Ingredients

  • 1 teaspoon of butter or Better (see tips, below)
  • 1 teaspoon olive oil
  • Cooking spray
  • 1/4 medium onion, finely chopped
  • 2 cups sliced mushroom caps (about 1/3 pound)
  • 3 1/4 cups vegetable stock (see tips, below)
  • 3/4 cup dry white wine
  • 2 cloves garlic, peeled and quartered
  • 1/4 cup unbleached all-purpose flour
  • 1 tablespoon golden miso (sweet white miso)
  • 1 tablespoon dark miso (traditional red miso)
  • 3 tablespoons nutritional yeast (see tips, below)
  • 1 teaspoon Dijon mustard
  • Salt and freshly ground black pepper, to taste

Method

  • 1.
  • Melt the butter and olive oil together in a large skillet, well sprayed with cooking spray, over medium heat for about 1 minute.
  • Add the onion and saute, stirring often, for about 4 minutes, or until the onion begins to soften.
  • Raise the heat slightly and add the mushroom caps.
  • Continue cooking, stirring often, for 5 to 6 minutes more.
  • 2.
  • Pour the vegetable stock into a medium saucepan or Dutch oven, preferably nonstick, and warm over medium-low heat.
  • 3.
  • Pour the wine into a food processor and add the garlic, flour, golden miso, dark miso, nutritional yeast, and mustard.
  • Buzz together to form a paste.
  • 4.
  • Whisk the paste into the warmed, but not hot, vegetable stock.
  • Gently bring to a boil, then reduce to a simmer.
  • Take a ladleful of this liquid and swirl it into the sauteed mushroom mixture, stirring well to scrape up any little flavorful bits from the bottom of the skillet.
  • Add the mushrooms, onions, and liquid to the pot with the stock, scraping the saute pan clean.
  • 5.
  • Reduce the heat to very low and let the sauce simmer very gently, stirring occasionally, for about 30 minutes.
  • Correct the seasonings with salt (you'll need little, if any, since miso is salty) and a lot of pepper.
  • Serve hot, ladled over whatever good thing you are serving.
