I keep thinking I'd already posted this, but it turns out I hadn't. So, while I ought to have taken pictures (now that I found my camera!), I didn't because I thought y'all knew this one. This is one of the easiest desserts on the planet to make, and it's beautiful to look at and tastes wonderful. Hope you enjoy!
1 sheet puff pastry
2 fairly ripe pears, 1 apple, 2 peaches, etc; cored and sliced thinly
1 tablespoon vanilla sugar (optional)
1/2 teaspoon lemon juice (optional)
1 beaten egg (optional)
Put puff pastry sheet on a baking sheet. Score with a one inch border, then dock the inside of the border (that means poke a bunch of holes with a fork). Arrange the fruit slices in concentric squares, not letting the fruit leave the scored border. Sprinkle with sugar and lemon, if using. Chill in fridge while your oven heats to 400F. Apply egg wash to the border, if desired. Bake 15 minutes. Cool on a rack, then transfer to a plate. Serves 8.
