In a large mixing bowl, add all the dry ingredients - flour, salt, baking powder, baking soda, cinnamon powder, and sugar and mix well.
2 cups All purpose flour, ¾ teaspoon Salt, 2 teaspoon Baking powder, ½ teaspoon Baking soda, ½ teaspoon Cinnamon powder, ½ cup Sugar
Grate cold butter directly into the dry ingredients, and mix with a fork often so that the pieces of butter are well distributed in the flour mixture. Alternatively, a pastry cutter may incorporate cold butter into the flour mixture.
½ cup Butter
Add lemon zest for additional flavor, blueberries, and ⅔ cup of cream, and mix just until the dough comes together. Do not over-knead the scone dough.
½ teaspoon Lemon zest, 1 cup Heavy cream, 1 pint Blueberries
Transfer the dough to a working surface, form a rectangle or disc, and then cut into approximately eight triangles. The thickness will be about 2 inches.
Transfer these to a parchment-lined baking sheet and refrigerate for 15 minutes. You can also refrigerate it overnight so the next morning, you can have a quick breakfast.
Brush the tops with the remaining heavy cream (⅓ cup) and sprinkle with coarse sugar.
2 tablespoon Sugar, 1 cup Heavy cream
Bake in a preheated 400 F oven for 25 to 30 minutes or until light golden brown.

2 tablespoon Butter, 5 tablespoon Maple Syrup, ½ cup Confectioner's sugar
