These are so good and moist. Make sure that you squeeze all the juice from the onion so that the patties don't fall apart. These are served with drained yogurt, which can be drained on a paper towel-lined colander for a few hours to overnight. The longer it sits, the drier the texture. Cooking time does not include the time for draining the yogurt. Recipe courtesy of Martha Stewart, with a few adaptations. **NOTE** do not use the food processor to grate the carrots, it makes them juicier and the patties will fall apart.
