Apple Rose Tart

1 . Stage

Whisk flour, sugar, and salt together in a bowl. Add butter and egg; mix with a fork until crumbly. Work dough with your hands until fully blended. Wrap in plastic wrap and refrigerate, about 1 hour.

2 . Stage

Preheat the oven to 400 degrees F (200 degrees C). Roll dough out to fit a 9-inch pie plate. Place crust in the pie plate and prick with a fork.

3 . Stage

Bake in the preheated oven for 10 minutes. Remove and let cool.

4 . Stage

Meanwhile, place sliced apples, sugar, butter, water, allspice, cinnamon, and cloves in a large pot; cook over medium heat until apples start to release their juices and are just malleable enough to curve while still holding their shape, 4 to 5 minutes. Remove apple slices to a plate, reserving cooking juices in the pot.

5 . Stage

Add diced apples to the cooking juices and bring to a boil. Cook until apples are mushy, 5 to 10 minutes.

6 . Stage

Transfer mushy apples to a medium saucepan. Place walnuts in the bowl of a food processor; process until finely ground. Add nuts to the apples; stir until a paste forms. Add cream; bring to a boil. Remove from heat.

7 . Stage

Whisk egg thoroughly in a small glass bowl. Add 1 tablespoon of the hot cream mixture, whisking vigorously to make sure the egg doesn't curdle. Repeat twice more. Pour egg mixture into the saucepan; mix to incorporate. Allow custard to cool, stirring often.

8 . Stage

Spread cooled custard evenly over the crust. Arrange apple slices on top, working from the outer edge to the center in concentric circles, overlapping the slices to look like a rose.

9 . Stage

Bake in the preheated oven until browned, about 50 minutes.
