Start by deforsting your puff Pastry for about 1 hour before baking. Once deforsted open up the sheet and place it on a baking sheet lined with parchment paper. Then gently roll it out using a rolling pin. set aside
Apples
Start on your apples. Peel, core and slice all your apples. Slices should be thin, getting about 20 slices per apple.
In a large bowl place your apples and lemon juice and toss together. Then add your cinnamon, nutmeg, clove, allspice, sugar, flour. Toss until evenly combined. Set aside and let rest for about 30 minutes to release juices.
Butter
Make your butter mixture. in a small bowl add your softened butter, brown sugar, cinnamon, nutmeg, and allspice. Using a fork smash your butter and mix until combined. Set aside
Assemble
Spread your butter on top of your puff Pastry leaving a 1 inch boarder around the edge. Place apple slices in a circular pattern on top of the butter, leaving an inch boarder around the edge. you can arrange these in any desired way. YOU MUST leave behind all the juices that are in the bowl. if you just dumb apples and juice into the crust you will have a sloppy mess.
pull the edges of the puff pastry up around the apples creating a crust. Brush that crust with an egg wash.
Bake galette at 375 degrees for 30 minutes.
Serve warm with vanilla ice cream and caramel if desired.
