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.
