The literal meaning of these gorgeous little turnovers is "wrapped in bread". Empanadas have become so popular that there are countless recipes to choose from. This is a deliciously satisfying option made with Jambon de Bayonne ham and bleu d'Auvergne cheese, which goes perfectly with a simple green salad.
Preheat the oven to 180 °C. Peel and finely slice the onions.
Sauté the onion with the butter in a pan. Season with salt and pepper, add the brown sugar. Leave for 10 minutes or so to caramelize. Cut the ham into strips.
Using a knife and a bowl, cut out 5 pastry disks. In the center of each disk, place a spoonful of onions, some ham, some small pieces of cheese and a few pine nuts.
Fold the empanadas into half-circles, crimping the edges with a fork to prevent the filling from leaking out during cooking.
Mix the egg yolk and the milk. Lightly brush the empanadas with this mixture.
Bake for 25 minutes.
