Peal apples and cut in 4

On a saucepan, melt the butter and spread a nice amount of the sugar

Arrange the apples with the round side down (towards the saucepan) and once the circle is done, a top layer with the round sides up. (just arrange them nicely)

Warm the pan for 10 to 14 min controlling with help of a butter knife that the sugar becomes golden-brown

heat the oven at 230 C, stretch the pastry dough keeping 2cm over the edge of the sauce pan. Push the edges carefully inside not disturbing the apples too much.

Bake 15 min in the oven and then lower the temperature to 180 C and cook another 15 min.

Place a plate over the baked dough, and fast flip it upside down (just in case do it over the sink). The whole tarte should fall on the plate in one piece.

Serve warm (best in my opinion) or cool (you can also serve it with cream or ice cream).

Enjoy!
