The Concierge's Potato Soup

myrialux and I made a fabulous soup tonight. It's from a cookbook I've owned for close to 30 years, long enough that the spine cracked (ok, the glue's not great) and half the pages fell out so I bought another copy. There's several recipes in there that are standards in my repertoire.

I'd never made this one, though. Not sure why, other than I've only recently become a Soup Person (and I still prefer creamy soups to ones made of lots of stuff in a thin broth). But our not-quite-a-CSA delivered a pound of carrots to us, and I wanted potatoes, and between me marking several recipes and making myrialux go through them and narrow them down, we ended up with this one.

The book is A Passion for Potatoes (affiliate link) by Lydie Marshall. There's at least one other potato-based cookbook with the same title, by Paul Gaylor. I have that one also, but it just doesn't have the same place in my life.
