Blend flour and salt briefly in a food processor. Add the chilled butter cubes and pulse until the mix looks like coarse crumbs with small butter chunks. Slowly add the icy water, one spoonful at a time, while pulsing, until it barely starts forming dough. Skip the last bit of water if it comes together sooner. Dump the dough onto a floured surface, mold it into a disc, cover with plastic wrap, and chill for 30 minutes or more.

Preheat the oven to 375°F (190°C) once you’re ready to start baking. Get a baking tray ready by lining it with parchment paper.

Toss together the apple slices with the brown sugar, cinnamon, lemon juice, and nutmeg in a big bowl. Stir gently to coat them all evenly.

Roll the chilled dough on a floured surface into a rough circle about ⅛-inch thick and 12 inches wide. Place it onto the parchment-lined tray.

Pile the apple mixture in the center of the dough, leaving about 2 inches at the border. Fold and pleat the edges over the apples, making sure the center stays uncovered.

Coat the pleated dough edges with the egg wash using a pastry brush, then generously sprinkle with sugar crystals.

Pop it into the preheated oven and bake for around 30–35 minutes until the crust turns beautifully golden and the apples soften.

Drizzle the warm galette with salted caramel straight out of the oven. Let it cool a bit, then slice and enjoy.
