POTATO AND KALE GALETTE

Steps:

• Cook kale in a 4- to 6-quart pot of boiling salted water, uncovered, until just tender, 4 to 6 minutes. Drain in a colander and rinse under cold water to stop cooking. Drain well, squeezing handfuls of kale to extract excess moisture, then coarsely chop.
• Heat 2 tablespoons (unmelted) butter in skillet over moderately high heat until foam subsides, then add garlic and cook, stirring occasionally, until golden, about 1 minute. Add kale, 1/4 teaspoon salt, and 1/4 teaspoon pepper and sauté, stirring, until kale is tender, about 4 minutes. Transfer to a bowl and clean skillet.
• Peel potatoes and thinly slice crosswise (1/16 inch thick) with slicer. Working quickly to prevent potatoes from discoloring, generously brush bottom of skillet with some of melted butter and cover with one third of potato slices, overlapping slightly. Dab potatoes with some of melted butter.
• Spread half of kale over potatoes and sprinkle with 1/8 teaspoon salt and 1/8 teaspoon pepper.
• Cover with half of remaining potato slices and dab with butter, then top with remaining kale. Sprinkle with 1/8 teaspoon salt and 1/8 teaspoon pepper. Top with remaining potatoes and sprinkle with remaining 1/4 teaspoon salt and 1/4 teaspoon pepper.
• Brush a sheet of foil with melted butter, then brush galette with any remaining butter and place foil, buttered side down, on top. Place a 10-inch heavy skillet on top of foil to weight galette.
• Cook galette over moderate heat until underside is golden brown, 12 to 15 minutes. Remove top skillet and foil. Wearing oven mitts, carefully slide galette onto a baking sheet and invert skillet over it. Holding them together, invert galette, browned side up, back into skillet. Cook, uncovered, over moderate heat until underside is golden brown and potatoes are tender, 12 to 15 minutes. Slide onto a serving plate.
