Place the cut-up strawberries on a baking sheet and bake/roast in a 250 F degree oven for 1 hour and 20 minutes -- this perfectly removes the juice from the berries so that it doesn't seep all over the dough! Set aside.
Preheat oven to 400 F degrees and cover a baking sheet with parchment paper.
In a large mixing bowl, whisk together the dry ingredients: cake flour, sugar, baking powder, baking soda, salt, and lemon zest (optional).
Grate the frozen stick of butter using a box grater or cut up into small 1" cubes. Mix the grated butter flakes into the dry ingredients with a pastry cutter until the batter has various sizes of coarse clumps. Place the scone dough into the fridge while whisking the wet ingredients together.
In a small bowl, whisk together ½ of the buttermilk (save the other 1/2 for brushing the scone tops) with the ricotta cheese, egg, and vanilla. *Again, save the other ½ of the buttermilk to brush the top of the scones before baking.
Slowly mix this wet mixture into the dry ingredients, using ⅓ at a time.
Do not overwork the dough. At first, the dough will feel a little wet and/or crumbly and then it turns into large clumps of dough.
With flour on your hands, form the dough into a round ball-like shape. If you feel that the dough is too dry, add a tablespoon of buttermilk until the dough comes together.
Place the dough ball on a lightly floured surface (I use a wooden board). Pat it and shape it into an 8" or 9" circular disc shape, about 1" thick.
Place the entire dough circle in the FREEZER for 20 minutes. This keeps the scones set and less likely to spread all over the baking sheet.
With either a knife or a bench scraper cut the dough into 8 triangles. Place these on a prepared baking sheet about 2" apart.
Glaze the scones before baking: Brush the remaining buttermilk on the top of the scones. Sprinkle turbinado sugar all over using the amount that you prefer.
Bake until golden brown, about 25 minutes.
Remove from the oven and allow the scones to cool a bit for 15 - 20 minutes.
Serve the scones warm with ricotta cheese, soft butter, and sweet strawberry jam.
If using the icing option, drizzle the icing randomly on the top of the scones.
