Vichyssoise or Purmentier: Cold or Hot Leek and Potato Soup

You can serve leek and potato soup hot or cold, depending on your weather.  When it’s cold you can add some cream and call it Vichyssoise and top with some chopped chives.  If you want hot soup, leave out the cream and garnish with croutons.

Cleaning Leeks

I grew leeks again this year and am really enjoying having them available.  You just have to know that they get a lot of dirt into their inner parts while growing so you need to wash them well. You can just slice them and wash them in a colander or you can trim the tops, leaving some of the green parts, and trim the root end off.  Lay the leek down with the root end away from you and slice it in half lengthwise starting about a half inch away from the root so it all holds together. Then turn it a quarter turn and do the same thing again. Then hold it under running water to rinse all the dirt and grit away.  Once it’s clean, lay it down on your cutting board and slice into 1/4″ slices or whatever you need.

  1. […] Leek and Potato Soup -One of my personal favorites, with or without the cream, warm or cold. It’s pretty much good anyway you serve it. Leeks can be a bit expensive sometimes, but they’re very easy to grow in the garden if you’re so inclined! […]
