Recipe for Anthony Bourdain’s Mushroom Soup from “Les Halles Cookbook” The recipe says Serves 4. We served 2 with nothing left over.
6 tbsp/75 g butter
1 small onion, thinly sliced
12 ounces/340 g button or cremini mushrooms
4 cups/900 ml light chicken stock or broth
1 sprig of flat parsley
Salt and pepper
2 ounces/56 ml high-quality sherry
(If you do not have ‘good’ sherry,omit this ingredient.
Cooking Sherry is NOT a substitute.)
Equipment
Medium saucepan
Wooden spoon
Blender
1. In the medium saucepan, melt 2 tablespoons/28 g of the butter over low heat and add the onion. Take the time to cook until the onion is soft and translucent.
2. 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 which is best achieved by low temperature cooking.
3. Stir in the chicken stock and the parsley and bring to a boil. Immediately reduce the heat and simmer for about an hour.
4. 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. 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.
