Grease an ovenproof dish (approx. 30 cm long). Wash, quarter and core the pears. Cut into slices and sprinkle with lemon juice immediately
Separate eggs. Beat egg white and salt until stiff. Mix quark, egg yolk, fat, milk flour, sugar, ground almonds and lemon peel. Fold in the beaten egg white. Layer quark mixture and pears in the mould. Sprinkle with breadcrumbs
Bake in the preheated oven (electric oven: 200 °C/circulating air: 175 °C/gas: level 3) for 40-50 minutes. After about 25 minutes, sprinkle almond flakes over the top and bake until done. Dust with icing sugar. Serve with vanilla or chocolate sauce
You can also bake the quark casserole with apples and hazelnuts. If you like, drizzle 2 tablespoons of pear or apple brandy while still hot
