Melt 2 tablespoons butter in a nonstick skillet over medium-high heat. Crush 1 cup egg noodles and add to the skillet. Cook, stirring, until browned, 3 to 5 minutes. Drain on paper towels; season with salt and pepper. Boil 1 pound egg noodles as the label directs. Reserve 1 cup cooking water; drain the noodles and return to the pot off the heat. Add 4 tablespoons butter, 2/3 cup crème fraîche, 2 tablespoons chopped chives, 2 teaspoons poppy seeds, 3/4 teaspoon nutmeg and 1/2 cup of the reserved cooking water. Stir until creamy, adding more cooking water as needed. Season with salt. Top with the fried noodles.
