BUCKWHEAT CREPE NOODLES WITH CHIVE BUTTER
3 cups whole milk
4 large eggs
1 cup buckwheat flour
1/2 cup all-purpose flour
1 teaspoon salt
1/4 teaspoon black pepper
1/3 cup finely chopped fresh flat-leaf parsley
5 tablespoons unsalted butter, melted
1/2 stick (1/4 cup) unsalted butter, softened
1/3 cup finely chopped fresh chives
Blend milk, eggs, flours, salt, and pepper in a blender, scraping down sides occasionally, until smooth, then add parsley and 3 tablespoons butter and blend just until incorporated. Lightly brush a 10-inch nonstick skillet with some remaining butter and heat over moderate heat until hot. Fill a 1/4-cup measure three-fourths full of batter, then pour into skillet, tilting and rotating skillet to coat bottom. (If batter sets before skillet is coated, reduce heat slightly for next crępe.) Cook just until underside is set and lightly browned, 10 to 15 seconds, then loosen crępe with a heatproof plastic spatula and flip over with your fingers. Cook crępe until other side is just cooked through, about 15 seconds more. Transfer crępe to a large sheet of wax paper. Make more crępes in same manner, lightly brushing skillet with more butter as needed between batches and stacking crępes in 2 piles.
Transfer crępe stacks to a cutting board and cut each stack into 1/2-inch-wide strips, then separate into noodles.
Put oven rack in upper third of oven and preheat oven to 350°F. Generously butter a baking pan. Spread noodles in baking pan and reheat in oven until hot, about 15 minutes.
Mash together butter and chives with a fork in a small bowl, then add salt and pepper to taste. Melt chive butter (along with any remaining melted butter from crępes) in a small saucepan, then drizzle over noodles. Gently transfer noodles to a warmed serving bowl. Serves 8.
