Potage Parmentier

I first stumbled on to Julia Child's recipe for potage parementier- that is, potato soup - in the book Julie and Julia, which is a story about a woman named Julie who cooked her way through Mastering the Art of French Cooking.
In the story, Julie is having a particularly bad day at the office, goes to the grocery store and buys a few random things and then proceeds to make potato soup, which is heavenly.
This week, I seem to have gotten some mysterious upper respiratory thing - which is unusual because A. It's June and B. I never get sick.
I get sick so rarely that when I do, I become a big whining baby who mopes about feeling tired and sorry for herself. So I was rereading Julie and Julia and read the part about Julie making potage parementier and thought, "this is exactly what I need right now."
Potage Parmentier has three ingredients: potatos, leeks and water.
Unfortunately, I didn't have leeks. But I did have three tiny onions from the CSA that were just begging to be a part of some delicious soup. So the potatos and onions got put into a pot with water and I wandered back to the couch for 45 minutes.
In the book Julie and Julia, Julie talks about how Julia (man that's confusing) says you should use a food mill to mash up the leeks and potatoes because the soup should have bits in it and not be totally smooth - because that would be "un-French." She uses a potato ricer instead.
Well too bad. I have neither a food mill nor a potato ricer. But I do have a very handy 3 cup food processor that whirred those potatoes, water, and onions into a smooth, velvelty soup that "smells good, tastes good and is simplicity itself to make."
Top with some fresh chives and a pat of butter and you have an incredible meal. While I enjoyed the book Julie and Julie, as well as the movie, I thought the whole "cook your way through a complicated French cookbook" was a little hokey. I mean I'm all for setting silly challenging goals, but that's a lot of butter. And I'm sure there are a lot of things in there I wouldn't like to eat.
I had contemplated buying the cookbook too, you know just to have it. But then I realized I have several cookbooks I never use now, so why get another tome to add to the collection?
After trying this recipe, though, I'm reevaluating that decision.
