I read this recipe at work, so when I went shopping I only had a mental list to go by. Only ended up with .5 lb of mushrooms, so I cut back on some ingredients. Used 1 large sweet potato, half large onion, 3T flour, 2T paprika, 1T dill, 3 c broth, 1 c milk. Would like it a little thicker, though, but still incredible. Next time will use white potato, the sweetness of the sweet potato was out of place. Only 2 of us in the household, so we reheat the soup and add the sour cream just before eating. I expect this to only be better when I make it again with full ingredients list.
