LED stands for light emitting diode.. A diode is an electrical component with two terminals which conduct the electricity only in one direction. With an electrical current, the diode emits a bright light around the small bulb.
Brush the fish with a mixture of butter, thyme, rosemary, black pepper and tarragon. Squeeze the juice of one lemon over the fish. Bake the speckled trout at 400 F for 20 minutes, or about 10 minutes per inch of thickness. Baste the fish after 10 minutes with the butter and herb mixture.
Melt butter in a saucepan over medium-low heat until butter smells toasted and is golden brown, about 1 minute. Turn off heat. Line a baking sheet with a piece of aluminum foil. Place trout onto foil; open trout so skin sides are down. Drizzle each trout with about 1/2 teaspoon melted butter. Generously season with salt and black pepper. Move an oven rack to 5 or 6 inches below heat source and preheat oven's broiler on high heat. Broil trout until opaque and barely firm to the touch, 2 or 3 minutes.
