• 1½ pounds apples, peeled, cored and sliced
• 2-4 tablespoons granulated sugar
• 2

Combine apples, sugar, butter and grated lemon rind in a saucepan, and simmer gently, stirring from time to time, until mixture is reduced to pulp. Beat mixture with a wooden spoon until perfectly smooth, or rub it through a sieve; then add beaten egg yolks.

Line a pie dish with shortcrust pastry and pour apple mixture into it. Bake in a moderate oven (<
