Instructions: Boil potato in salted water to cover until it is tender but not mushy, 30 to 40 minutes.

Meanwhile, place fish in a skillet that can later be covered. Add water to cover, salt the water, and bring to a boil over high heat. Cover, turn off heat, and set a timer for 10 minutes. After that time, use a slotted spoon to remove fish to a bowl.

When potato is done, peel it and mash it with the fish. Add ginger, cilantro, hot pepper, and salt and pepper to taste. Work mixture with your hands until it is well blended. Shape into 8 burger-shaped patties.

Preheat broiler; set rack about 4 inches from heat source. Brush patties on both sides with oil, then place on a nonstick baking sheet. Broil carefully, until nicely browned on top; turn and brown on the other side.

Sprinkle with more cilantro. Serve hot with lime wedges.

Yield: 4 servings. Approximate nutrition information per serving: 255
