Preparation Lightly oil an 8- by 4-inch loaf pan (6-cup capacity) and line with parchment paper, leaving a 2-inch overhang at each end. Whisk together water, chickpea flour, sea salt, and 2 tablespoons oil in a 2 1/2- to 3-quart heavy saucepan until smooth, then cook over moderate heat, stirring constantly with a wooden spoon (to prevent lumps from forming), until very thick and mixture pulls away from side of pan, 20 to 25 minutes. Transfer mixture to loaf pan, smoothing top. Cool, uncovered, then chill, surface of mixture covered with plastic wrap, until firm, at least 3 hours. Lift chickpea block out of pan using parchment and transfer to a work surface. Gently flip over block and discard parchment, then pat dry. Cut block crosswise into 1/4-inch-thick slices for panelle. Preheat oven to 300°F. Heat 1/2 inch oil (about 2 cups) in a deep 10-inch heavy skillet until it registers 375°F on thermometer, then fry panelle in 5 batches, carefully turning occasionally with tongs, until golden and puffed, 3 to 5 minutes per batch, and transfer to paper towels to drain. Keep warm on a baking sheet in oven while frying remaining batches. Arrange panelle on a platter and sprinkle with parsley and cheese. Serve immediately. Cooks' NoteIf your sea salt is very granular and pebblelike, crush it using the flat side of a large heavy knife or the bottom of a heavy skillet. To take the temperature of a shallow amount of oil, put bulb in skillet and turn thermometer facedown, resting other end against rim of skillet. Check temperature frequently. Chickpea mixture can be chilled in loaf pan up to 1 day. Panelle can be fried 4 hours ahead and kept, uncovered, at room temperature. Reheat on a baking sheet in a preheated 350°F oven 10 to 15 minutes. Chickpea flour is available at Italian markets, many specialty foods shops, and D. Coliccio & Sons (718-436-6700).
