Classic Vichyssoise Soup Recipes

Steps:

• Start the chicken stock 2 days in advance: Trim away all green sections from the leeks; cut open the whites as necessary to wash out the grit, then dry and refrigerate in a plastic bag. Wash and reserve the leek greens.
• Wash the chicken backs, poking into the crevices with your finger to rinse away all bits of liver. (Chicken backs are best because they don't make an overly gelatinous stock; for cartilaginous parts like breast trimmings or wings, use only a pound.).
• Simmer the chicken and 1/4 teaspoons salt for 6 hours in water to cover, skimming off all scum (don't try to remove the fat); after 2 hours, add some or all of the leek greens. Strain the stock finely, making about 2 cups; cool and refrigerate. Before using, scrape off the congealed fat.
• Cook and refrigerate the soup base 1 day in advance: Saute the onions in a heavy 2-quart saucepan, starting on fairly high heat and reducing to medium as soon as the fat clarifies. When the onions are golden, increase the heat and add the leeks gradually; lower the heat again as they cook, stirring repeatedly to keep the juices from browning.
• In 15 to 20 minutes, when everything is golden but not browned, add the stock and 3/8 teaspoons salt, and bring to a boil. Add the potatoes, partially cover the pan, and simmer actively for 35 minutes. (Don't use too much potato, or the soup will end up too thick.).
• In two batches, finely puree the soup base in a blender at high speed, then pour it back into the saucepan. Rinse out the blender with the milk, add it to the soup base, and heat slowly until it just starts to simmer, stirring continually across the pan bottom and around the sides.
• Finally, put the soup through a very fine strainer, scraping hard with a rubber spatula to push everything through. Cool quickly and refrigerate.
• On serving day, stir the cream gradually into the softly jelled soup. Carefully adjust the consistency, adding more cream (or water or both) as necessary to make a thick but pourable liquid; a spoonful poured back into the bowl should level out, not stay in soft peaks. Taste for seasoning -- don't oversalt, or you'll lose the natural sweetness of the onion and cream.
• Vichyssoise keeps refrigerated up to 10 days.

Steps:

• In a large stock pot melt butter over low heat. Add leeks and onion, cover, and cook for 10 minutes.
• Add potatoes and season with salt and pepper. Add thyme, marjoram, bay leaf and stir well. Cover pot and continue to cook for 12 minutes.
• Add chicken stock and bring to a boil, reduce heat and cook, partially covered for 30 minutes.
• Puree soup in blender or food processor and cool.
• Prior to serving add cream. If you are serving this soup warm you need to reheat the soup slowly so that the cream does not change consistency.

Steps:

• Put the leeks, potatoes, celery and onions in a pot. Add mineral water to cover and season with salt and pepper. Cover, bring to a boil and simmer until very tender. Puree and strain into a glass bowl. Thin with the cream, and with more liquid if needed. Let cool, then chill.
• Before serving, thin the soup to the desired consistency with more water or milk. (You can also use chicken stock, but if you're trying to be vegetarian, then obviously don't.) Check the seasonings. Serve sprinkled with chives.

Steps:

• I a large, heavy bottom pot, melt butter over medium-low heat. Once butter is melted, add the leeks and sweat for 5 minutes, making sure they do not take on any color.
• Add potatoes and cook for a minute or two, stirring a few times.
• Stir in the chicken broth and bring to a boil.
• Reduce heat to a simmer. Cook on low heat, gently simmering for 35 minutes, or until the leeks and potatoes are very soft. Allow to cool for a few minutes.
• Slowly, and in SMALL batches, puree the soup at a high speed in the blender. Do this bit by bit, never filling the blender too high. Make sure the benders lid is on, and lean on the top when you turn on. If not the burn you will get is awful, and a most frequent accident in even professional kitchens.
• Return soup to the cooking pot and whisk in cream and nutmeg. Season with salt and pepper. Return to a boil, reduce to simmer and cook 5 minutes. If you want to thin soup out, add more broth, if needed.
• Transfer soup to the mixing bowl an chill over the ice bath, stirring occasionally. When soup is at Room temperature, and only at room temperature, cover in plastic wrap and put into the refrigerator to cool.
• Check seasoning, sprinkle with chives and serve in chilled bowls.
• This soup DOES get better over time. Keep covered with plastic, not foil in the refrigerator, or it will pick up other tastes.

Steps:

• Melt the butter in the pressure cooker pot over medium-low heat. Add the leeks, celery leaves and 1 teaspoon of the salt and cook, stirring often, until soft, approximately 8 minutes. If the leeks start to brown during this process, reduce the heat.
• Drain the potato pieces and add to the pot along with the simmering chicken broth. Clamp on the cooker's lid, (according to the manufacturer's instructions) and bring to full pressure over high heat.
• Once pressure is attained (there will be a loud whistle) back the heat down to medium-low, just maintaining a hissing of steam for 8 minutes.
• Kill the heat and release the steam pressure by opening the dump valve or setting the cooker under cold, running water. When the lid can be removed, carefully transfer the mixture to a blender carafe. (If the mixture fills your carafe more than two-thirds full, work in two batches!)
• Top the carafe with the main lid but remove the center lid so that air can escape as it heats and expands. Cover the lid tightly with a tea towel and blend on low for 1 minute before slowly increasing the speed to smoothly puree the potatoes. (Although you want to increase the speed slowly, try not to puree the potatoes too long as they could become gummy.)
• Transfer the mixture back to the pot and whisk in the cream. Stir in the white pepper. Taste and adjust the seasoning (I always need the rest of the salt). Chill thoroughly then serve garnished with a small spoonful of the roe and dill fronds.
• Tightly covered, the vichyssoise will keep a week in the refrigerator. The soup can also be frozen in ice-cube trays then kept in freezer bags for up to three months.
