Olivier Baussans Chestnut Soup Recipes

ROASTED CHESTNUT SOUP

Steps:

• If you have skinned chestnuts, proceed to step 2. If your chestnuts still have their skins, preheat the oven to 350°F. Use a sharp (preferably curved) paring knife to make an X on their flat sides. Roast them in one layer in a baking pan for 10 to 15 minutes, or until their skins begin to open away from the meat. They will then be easy to peel; remove both outer and inner skins while they are warm. (The peeled chestnuts will cook faster if you chop them roughly, but it isn't necessary.)
• Meanwhile (if you have skinned chestnuts, start here), put the olive oil or butter in a deep skillet or casserole over medium heat. A couple of minutes later, add the celery, onion, and a good sprinkling of salt and pepper and cook, stirring occasionally, until the onion is translucent, about 10 minutes. Add the stock and the chestnuts, bring to a boil, and partially cover. Adjust the heat so that the mixture simmers and cook until the chestnuts are mushy, about 30 minutes.
• Carefully puree the soup in a blender (if you are not in a hurry, cool it slightly first for extra caution). Measure and add water to make 6 cups of liquid. Reheat, adjust the seasoning if necessary, garnish with celery leaves or parsley, and serve.
• Variations
• I like to elaborate on this soup in two ways, depending on what I've got in the fridge and whether meat eaters are coming to dinner:
• Chestnut Soup with Bacon: Start by rendering 1/4 cup or so of diced slab bacon; scoop out the solids and reserve them for garnish, then sauté the celery and onion in the rendered fat and proceed as directed.
• Chestnut Soup with Shiitakes: Garnish the soup with a cup or so of shiitake mushrooms (caps only), sliced and sautéed in butter or oil until crisp.

CHESTNUT SOUP WITH BACON AND CHIVES

Steps:

• In a large saucepan over medium heat, cook bacon until rendered and crisp, 8 to 10 minutes. Transfer bacon to a paper towel-lined plate. Pour off all but 1 teaspoon of the fat. In the same saucepan, melt the butter, and add the carrot, celery, leek, and shallots. Season with salt and pepper. Cook over medium-low heat until softened and golden brown, 8 to 10 minutes.
• Add broth and chestnuts to the saucepan. Bring to a simmer, partially cover, and cook until all the ingredients are soft, about 30 minutes. Let cool slightly, and purée in batches in a blender until very smooth. Return to saucepan, add the cream, and heat thoroughly, adding stock to thin if needed. (A spoon should not leave a trail on the surface of the soup.)
• Season with salt and pepper and ladle into warmed shallow bowls. Garnish with the reserved bacon, a dab of crème fraîche, chives, and a pinch of nutmeg.

OLIVIER BAUSSAN'S CHESTNUT SOUP

Steps:

• Preheat the oven to 350 degrees. Cut through one end of the shell of each chestnut. Place them on a sheet pan and roast until browned and the skins begin to pull back, 7 to 8 minutes. When cool, peel the nuts and discard the skins.
• Melt butter in a large soup pot. Add shallots and cook until soft. Add chestnuts, raise heat and cook, stirring, until chestnuts are golden. Stir in the porcini powder, vinegar and 4 cups of water. Add 2 cups of the cream and stir, scraping any residue from the bottom. Lower the heat and simmer for 20 minutes.
• Bring the remaining cream to a boil and add the cardamom pods. Remove from the heat, cover, and let sit for 10 minutes. Strain and season with salt and pepper.
• Purée soup in a blender and stir in the truffle oil. Reheat the soup. (It should be warm, not piping hot.) Season with salt and pepper if necessary. Whip the infused cream until very frothy. Ladle soup into 8 small mugs and top with the frothy cream and a pinch more porcini powder, if desired.
