This sounds great. I especially like that non-dairy creamer can be substituted for half and half. I'm going to try this out very soon!
this has a wonderful flavor although i did make mine a bit differently to save on cleanup. i sauteed the leeks, etc in a large pot, then added the potatoes, stock and cooked for 20 minutes until potatoes were tender. i used a hand blender to puree it all, then added the cucumbers and chilled. i garnished with fresh chives, this was delicious.
