I also did not when to add the sour cream so just omitted it. Nice flavour without and my soup was really thick but I did not use all the stock and might of added more potatoes or used bigger one so IMO did not need it. Made for PAC Fall 2009
The recipe is incomplete & I made several adjustments so am only leaving comments. The addition of the sour cream is not included in the directions. I elected to temper it & still had a few curdles. The soup was extremly thin and cntaind no thickening agents. It tasted good with the bay leaves and garlic (used 3 cloves). I topped the bowls with dustings of smoked hot paprika & chives.
