Preheat oven to 400F and line a baking sheet with parchment paper. Place butter in the freezer for 10 minutes.
In a bowl, mix flour, shredded coconut, salt, baking powder, baking soda, and sugar.
In another small bowl, mix blended cottage cheese, lemon juice, and lemon zest.
Add wet ingredients to dry and mix until just combined.
Grate cold butter into the dough, mixing as you go to evenly distribute.
Form dough into a ball, roll into an 8-inch circle, and cut into 8 wedges.
Place them on a baking sheet and spread them out so there is plenty of space in between.
In a small bowl, whisk together the egg and water to make the egg wash.
Brush each wedge with egg wash.
Bake for 18–20 minutes, until lightly golden.
Cool slightly.
Optional: mix glaze ingredients and drizzle over scones if desired. Serve.
