Preheat oven to 425℉
Mix Flour, Sugar, Baking Powder, Salt, and Lemon Zest in bowl of electric mixer with the paddle attachment.
In separate, small bowl, add the Huckleberries. Stir in the Lemon Juice. With the berries covered in juice, add 1/4 cup of the flour mixture to the berries. Stir to coat the berries with the flour.
Pop the bowl of berries in the freezer to keep frozen while you finish up the dough.
Add the Butter pieces to the flour. Mix on low speed to incorporate the butter into the flour mixture until it forms pea-sized crumbles. You may need to finish this process with your hands by rubbing the butter and flour together between your fingers, until you get pea-sized crumbles.
Make a well in the middle of the flour/butter mixture and add the Heavy Cream. Mix on low until a dough begins to form.
Once most of the flour is combined into the dough, remove bowl from mixer and add the flour-coated berries. Gently press and stir berries into dough. You probably won't be able to combine them all, which is okay.
Dump out dough, and any stray berries onto a large piece of parchment paper.
Gently "knead and press" the stray berries into the dough until they are evenly distributed. Form the dough into a rectangle that is roughly 9" x 6".
Cut the dough in half horizontally, then cut vertically into 3 sections, leaving you with (6) 3"x3" squares.
Separate your squares and cut each diagonally, giving you 12 triangle scones.
Add scones to parchment lined baking sheets. Brush with Heavy Cream and sprinkle with Turbinado Sugar.
Bake at 425℉ for about 25 minutes, or until golden brown and puffed. Transfer to wire rack and cool for at least 10 minutes before serving.
