I got this recipe from a restaurant in Baltimore, Maryland many years ago. When the chef gave it to me, he, accidentally on purpose, left out the Cream Sherry, but I knew to include it. You can purchase crab roe from Charleston Seafood. It is $18.37 for 1 lb. (frozen) (shipped overnight). You can contact them at www.charlestonseafood.com or 1-(888) 609-3474. A substitute for crab roe are the yolks of hard boiled eggs. Your guests will absolutely love this VERY EASY TO MAKE SOUP.
