Wax Bean Soup Recipes

Does anyone have a recipe for a hot soup using yellow wax beans and sour cream? My mom used to make this, but I never wrote down the recipe and now she's gone. Any recipes would be really appreciated (by me and my sister!)

Thanks!

search engine?

My Mother in law used to make a soup she called blood soup . She uses apples raisins, dates ,duck and some of the blood mixed with floor has any one heard of this?
and does anyone have a recipe. Thanks

My Mom made it all the time too but she didn't use apples or raisins, she used prunes. I don't have the recipe though. It's called "czarnina".
