Ingredients
- 2 tablespoons butter
- 2 tablespoons corn or peanut oil
- 4 large onion, very thinly sliced
- 2 leeks (white part and 1-inch green part), split open lengthwise, washed well, and thinly sliced
- 4 cups vegetable stock
- 1 cup fresh cider, cooked down to 1/4 cup
- 1/4 cup brandy (Cognac)
- 2 medium organic russet potatoes, peeled and diced
- 1 bulb organic garlic cloves, separated and peeled
- 2 bay leaves
- 2 teaspoons fresh thyme or 1 teaspoon dried thyme
- 1 tablespoon light miso or soy bean paste
- Fresh ground nutmeg to taste
- 2 tablespoons cornstarch
- 1/3 cup heavy whipping cream
- Scallions, finely chopped for garnish
- 1 cup heavy whipping cream (for the creme fraiche)
- 2 tablespoons cultured buttermilk
Directions
- Prepare the creme fraiche: In a quart glass jar with a tight fitting lid, combine the 1 cup cream and 2 tablespoons buttermilk.
- Shake the cream and buttermilk hard for about 30 seconds to combine. Makes 1 1/2 cups.
- Let stand in a warm place or in a turned off oven with the pilot light on. Leave until thickened but still a little liquidy, about 12 hours. It sets up as it chills. It may be used right away, but is best after "aging" overnight in the refrigerator.
- In a large skillet, heat the butter and oil over medium-low heat.
- Add the onions and leeks; sauté slowly until quite limp, about 30 minutes.
- In the meantime, bring the stock, cider, brandy, potatoes, garlic, bay leaves, and thyme to a boil in a heavy soup pot.
- Turn down the heat to medium-low and let simmer, covered, until the potatoes are quite soft, about 30 minutes.
- Drain well, returning the stock to the pot. Remove the bay leaves and discard.
- Transfer mixture to a food processor, add the miso and creme fraiche, and puree.
- Stir the sautéed onions and the puree into the stock.
- Season with nutmeg, salt and plenty of pepper.
- To finish the soup, heat it almost to a boil.
- Dissolve the cornstarch in the cream and stir it into the soup.
- The soup will thicken almost immediately and have a clear, glossy finish. Serve very hot, in small cups, garnished with chopped scallions.
