Step 1Rinse, trim and peel beets, and then shred them on the coarse side of a grater to yield about 8 cups. Place the beets in a strainer or colander set over a bowl, and let stand 10 minutes to drain. Press the beets with a towel to remove any excess moisture, then place in a medium bowl.
Step 2Stir the cumin, coriander, parsley (or cilantro), salt, black pepper and baking powder into the beets, using a wooden spoon. Stir in the eggs, then the flour, and mix well to combine.
Step 3In a large frying pan, heat 5 to 6 tablespoons oil over medium heat until hot. For each latke, drop one-third cup of the beet mixture into the pan, flattening slightly with a spoon. Fry 4 to 5 latkes at a time, about 4 to 5 minutes on each side until deep red throughout and just lightly browned on the outside. Transfer the latkes to a paper towel-lined plate to drain. Repeat until all of the latkes are cooked, adding additional oil as necessary for frying. Serve warm.
