Wash, pare and cut potatoes in thin strips, using same slicer as for Lattice Potatoes. Soak in cold water fifteen minutes, drain, and dry between towels. Line a fine wire strainer of four-inch diameter, and having a wire handle, with potatoes, place a similar strainer, having a two and one-half inch diameter, in larger strainer, thus holding potatoes in nest shapes. Fry in deep fat, taking care that the fat does not reach too high a temperature at first. Keep the small strainer in place during frying with a long handled spoon. Carefully remove nests from strainers. Drain on brown paper, and sprinkle with salt. Fill with small fillets of fried fish or fried smelts.
