Apple Crumble Parfait

Preheat oven to 350 degrees F.

For topping, beat butter and sugars until light and fluffy. Beat in egg and vanilla. In a separate bowl, stir flour, salt, baking powder and nutmeg to combine. Add to butter mixture and combine just until blended. Wrap and chill until firm. With cheese grater, grate crumble topping onto a parchment lined baking sheet and sprinkle with demerara sugar. Bake at 350 degrees F. for 18 to 20 minutes, until golden brown.

Preheat oven to 375 degrees F.

For fruit, toss diced apples with lemon juice in a 10-cup baking dish, then add sugar and cinnamon. Bake fruit for 1 hour minutes, until apples are tender.

Bring cream just below a simmer over moderate heat. In a bowl, whisk sugar and egg yolks. Slowly pour hot cream over sugar mixture, whisking constantly. Return mixture to low heat and stir with a wooden spoon until sauce coats the spoon, about 4 minutes. Strain and stir in calvados or brandy. Chill completely before serving. Makes about 1 cup.

To assemble, whip cream with sugar to medium peaks.

Layer baked apples, crumble topping, custard and lightly sweetened whipped cream in parfait glasses and serve.
