VICHYSSOISE (INA GARTEN) RECIPES

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. 

Steps:

• Chop the leeks into small pieces.
• In a 6-quart saucepan over medium heat, melt the butter. Add the leeks and a heavy pinch of salt and sweat for 5 minutes. Decrease the heat to medium-low and cook until the leeks are tender, approximately 25 minutes, stirring occasionally.
• Add the potatoes and the vegetable broth, increase the heat to medium-high, and bring to a boil. Reduce the heat to low, cover, and gently simmer until the potatoes are soft, approximately 45 minutes.
• Turn off the heat and puree the mixture with an immersion blender until smooth. Stir in the heavy cream, buttermilk, and white pepper. Taste and adjust seasoning if desired. Sprinkle with chives and serve immediately, or chill and serve cold.
