You want to use stale rye bread for this. If you haven't any, just toast or bake and let cool. Roasted beets make everything sweeter and nuttier. Unusual, yet tasty. It's both sweet and savory; good for those times when you want dessert for dinner. Prep time does not include roasting the beets or making the bread stale. Do both of those yesterday. Prep time does include the part where you let the bread soak. Whisk the eggs, grate the beets and have a drink while that's happening. Adapted from Sheila Lukins' Around the World Cookbook. She translated the recipe from a Cyrillic recipe card.
