Preheat oven to 375°F
Take dough out of the fridge and place between two pieces of parchment paper lightly floured on both sides. Take your rolling pin and roll the dough, always start from the center and roll outwards, rotating the dough a quarter turn each roll. Continue rolling until you achieve 1/4 inch thick dough that is circular. Tip: never roll back on the dough, it will cause it to shrink.
Then, place in the freezer on a cookie sheet for 5 mins.
In a bowl, add berries, spices, honey, sugar, cornstarch, and lemon. Mix together until all ingredients are well incorporated. Set aside.
Remove dough from freezer. Using a spatula (or offset spatula) spread the cream cheese on the chilled dough. Ensure you leave 1.5" border around edge of dough. Next, pour the blueberry filling over top following the line of the cream cheese.
To create the edge/crust of the galette take the 1.5” border and fold it up into itself like folding a paper fan. Slightly pressing so it sticks to itself.
Once the entire border is made, apply the whisked egg with a pastry brush generously to the crust. Add sliced almonds and sprinkle with granulated sugar. Lastly add an extra little drizzle of honey over the blueberries.
While still on parchment paper, place on a baking sheet and slide in the freezer for 5 mins. Once 5 mins are up, place in oven on baking sheet and bake for 40-45mins, or until golden brown.
Remove and let cool on a baking rack for 1 hour before removing it from the baking sheet.
