I tried the Potato soup from Claire's Corner Copia, and it was not that good. I felt like it had way too much butter in it for it to be so boring.
So, next time I am going to try this potato soup from Simply Recipes... the website where the eggplant parmesan and potato-spinach-sausage casserole (which I tampered with here) came from. It looks really good, and I like the fact that it could quite easily be dairy free.
I think I might do regular old onions instead of leeks though... and bacon instead of ham??
