In a bowl, combine ground almonds, powdered sugar, cinnamon, and ginger. Mix well.
Add orange blossom water and melted butter to the almond mixture. Mix until well combined.
Stir in the egg yolk to bind the mixture. Set aside.
In a small saucepan, combine honey, water, and lemon juice. Heat over medium heat until the mixture starts to boil. Reduce heat and let simmer for about 5 minutes, or until slightly thickened. Remove from heat and let cool.
Preheat your oven to 375°F (190°C).
Lay out one sheet of pastry on a clean surface. Brush with melted butter or oil. Place another sheet on top and brush with more butter.
Place a small spoonful of the almond filling near one edge of the pastry.
Fold the sides over the filling to form a neat package. Roll up the pastry from the edge with the filling to form a log or triangle shape, depending on your preference.
Place the briouats on a baking sheet lined with parchment paper. Brush the tops with more melted butter or oil.
Bake in the preheated oven for 15-20 minutes, or until golden brown and crispy.
While still warm, dip each briouat into the cooled syrup or brush with syrup to coat.
Allow to cool completely before serving.
Enjoy your meal!
