My name is Leah, but I am not "Mama Leah" Mama Leah is a New York Jewish woman who has a restaurant and a cookbook, I believe. Cold Beet Borscht is a staple of Eastern European Jewish food. All recipes vary, each offering a little something different. This one is served cold with a hot potato in it. Truly meatless for those vegetarian folks.. The unique blend of hot and cold is something different, that I enjoy. Also splendid on a hot day. (Came from Mama Leah's Jewish Kitchen" hint: wear old clothes or an apron when preparing beets! THEY STAIN!
