Preheat oven to 180ºC . Butter and flour a 23 cm springform pan. In a bowl, cream the butter and 1 cup of the sugar together until light and fluffy. Add the egg yolks one at a time, beating well after each addition. Add the bread crumbs and all but a scant quarter cup of the pistachios. Beat 1 minute to combine. Set aside. In a separate copper or stainless bowl, beat the egg whites until soft peaks form. Add remaining tablespoon of sugar and continue to beat until soft dry peaks form. Whisk one third of the whites into the pistachio mixture to lighten. Then gently fold in the remaining whites. Pour into the prepared pan and smooth top with a spatula. Bake 30 to 35 minutes, or until a cake tester inserted in the center comes out clean. Cool in the pan on a wire rack for 1 hour. Remove the sides of the springform pan and continue to cool torte completely. Spread 1 cup of the lemon curd garnish on top and sprinkle with the reserved pistachios. Serves 8 to 10
