Preheat oven to 400 F. Place potatoes on a baking sheet and roast for 20-25 minutes or until completely softened.
Let potatoes cool, peel skin and place then in a large bowl of a mixer.
Add salt, ginger and cinnamon. Beat until no lumps in the potatoes. Beat in one egg at a time until smooth.
Add in honey and brown sugar and beat for another minute until well incorporated.
Preheat oven to 350 F. Line a few large baking sheets with parchment or a silicone mat.
Lightly dust surface with flour. Unroll one portion of puff pastry and roll it out with a rolling pin gently just enough to make it even thickness. Cut into 6 even rectangles and place the rectangles on the baking sheet lined with parchment paper. Cut the remaining sheets of puff pastry into matching pieces.
Divide the sweet potato filling onto 9 of the rectangles on the baking sheet and then top each with the second rectangle piece of puff pastry. Using a fork, crimp the edges of the hand pies to seal them. You should get 9 hand pies out of the recipe.
Cut 2 slits on the top of each hand pie with a serrated knife. Whisk together the egg and a tablespoon of water and brush over each hand pie.
Bake pies in preheated oven for 20 minutes until golden and puffy.
Serve with a dollop of creme fraiche, a good drizzle of honey and garnish with almonds.
