WILD YELLOW MUSHROOMS RECIPES

Steps:

• Heat the oil in a medium saute pan or skillet (not nonstick) over medium-low heat. Add the garlic and cook until fragrant, about 2 minutes (do not let the garlic brown). Push the garlic off to the side of the pan and add the mushrooms. Increase the heat to medium high and season the mushrooms with salt and pepper to taste. Cook, stirring occasionally, until the mushrooms are cooked through and begin to become golden in spots, 10 to 12 minutes.
• Add the spinach, sprinkle with an additional pinch of salt and turn with tongs until wilted. (If you can't fit all the spinach in the pan, cover it for a few minutes, then uncover, stir and add the rest.) Transfer to a serving platter, drizzle with the vinegar and serve warm.

Steps:

• Clean the mushrooms by wiping them with a dry paper towel. Don't wash them! Separate the stems, trim off any bad parts, and coarsely chop the stems. Slice the mushroom caps 1/4-inch thick and, if they are big, cut them into bite-sized pieces. Set aside. 
• To make the stock, heat the olive oil and 1 tablespoon of the butter in a large pot. Add the chopped mushroom stems, the onion, carrot, the sprig of thyme, 1 teaspoon salt, and 1/2 teaspoon pepper and cook over medium-low heat for 10 to 15 minutes, until the vegetables are soft. Add 6 cups water, bring to a boil, reduce the heat, and simmer uncovered for 30 minutes. Strain, reserving the liquid. You should have about 4 1/2 cups of stock. If not, add some water. 
• Meanwhile, in another large pot, heat the remaining 1/4 pound of butter and add the leeks. Cook over low heat for 15 to 20 minutes, until the leeks begin to brown. Add the sliced mushroom caps and cook for 10 minutes, or until they are browned and tender. Add the flour and cook for 1 minute. Add the white wine and stir for another minute, scraping the bottom of the pot. Add the mushroom stock, minced thyme leaves, 1 1/2 teaspoons salt, and 1 teaspoon pepper and bring to a boil. Reduce the heat and simmer for 15 minutes. Add the half-and-half, cream, and parsley, season with salt and pepper, to taste, and heat through but do not boil. Serve hot.
