Food / Polish Duck Soup [117]

My mother, cousin to the late Bishop Alfred Abramowicz, the "Polish Prince" of Chicago. Is approaching her late years and craving Duck Soup. She used to make it homemade for us 5 kids and we all knew it as "chocolate soup". We all loved it as children but as part of the generation of fast food, fat free food, and wash your hands until they bleed, I guess we all kind of gave up on the whole, "Duck blood is good for us." thing. Thank God for age and wisdom! Now we are all craving this nutritious soup and can find no supp;ier of duck blood in the Chicago area. On Easter, my mom (She still cooks Polish sausage, ham, the onion skin eggs, lambs cakes, along with dunplings and so many dishes), well she told me she has dreams of eating duck soup again-she calls it "Blood Soup"- she's 73. Any advice would help. I'm looking in the yellow pages but to no avail......thanks
