Boil potatoes until soft. Drain, combine with lime juice, salt and pepper, and grind process to a smooth batter. With greased hands, shape the batter into 1-inch balls and roll the balls in flour.
Make a condiment to pass around with the balls by mixing coconut and pepper with 2 or 3 tablespoons of water. Set aside.
In a heavy skillet or pot, heat oil to about 375 degrees, and fry the balls a few at a time. Drain on clean, absorbent cloths, and serve hot. Pass around the coconut/ pepper mixture for individuals to serve themselves.
