Longwood Gardens Mushroom Stock Recipes

Steps:

• In a 2 quart saucepan, melt butter and stir in flour until smooth.
• Gradually stir in broth until smooth. Add salt, pepper and bay leaves.
• Simmer, uncovered, for 15 minutes, stirring occasionally.
• Meanwhile, in another saucepan, saute the celery and onion in oil until tender. Add mushrooms; cook and stir until tender.
• Add veggies to broth mixture and bring to a boil. Reduce heat and simmer, uncovered for 15 minutes, stirring occasionally.
• Add cream and heat through. Discard bay leaves and serve.

Steps:

• Mince carrots, onions, and celery in a food processor and saute in heavy pot with oil. Mince mushrooms in a food processor, add to pot along with tarragon, salt, and pepper. Cook for about 15 minutes. Do not burn.
• Add stock and cream and bring to a boil. Mix melted butter and flour until smooth and whip into soup. Bring to a boil, stirring constantly until all of the flour and butter mixture is incorporated and the soup is thickened. Simmer for 30 minutes and serve. Adjust seasonings with salt and pepper, to taste.

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.

Steps:

• Method
• In the medium saucepan, melt 2 tablespoons/28 g of the butter over medium heat and add the onion. Cook until the onion is soft and translucent, then add the mushrooms and the remaining butter. Let the mixture sweat for about 8 minutes, taking care that the onion doesn't take on any brown color. Stir in the chicken stock and the parsley and bring to a boil. Immediately reduce the heat and simmer for about an hour.
• After an hour, remove the parsley and discard. Let the soup cool for a few minutes, then transfer to the blender and carefully blend at high speed until smooth. Do I have to remind you to do this in stages, with the blender's lid firmly held down, and with the weight of your body keeping that thing from flying off and allowing boiling hot mushroom purée to erupt all over your kitchen?
• When blended, return the mix to the pot, season with salt and pepper, and bring up to a simmer again. Add the sherry, mix well, and serve immediately.
• Improvisation
• To astound your guests with a Wild Mushroom Soup, simply replace some of those button mushrooms with a few dried cèpes or morels, which have been soaked until soft, drained, and squeezed. Not too many; the dried mushrooms will have a much stronger taste, and you don't want to overwhelm the soup. Pan sear, on high heat, a single small, pretty, fresh chanterelle or morel for each portion, and then slice into a cute fan and float on top in each bowl.
• And if you really want to ratchet your soup into pretentious (but delicious), drizzle a few tiny drops of truffle oil over the surface just before serving. Why the hell not? Everybody else is doing it.
