Set butter in freezer for 20 minutes so it can get cold enough to grate easily.
Preheat oven to 425°
Combine milk and lemon juice and set aside in fridge to keep cold
In a large bowl, combine: flour, baking soda, sugar and salt. Whisk together and set aside.
After butter has chilled for 20 minutes, grate butter (using a cheese grater) into the dry ingredients.
Using a fork or very clean fingers, gently mix and massage the butter into the dry ingredients until a sandy-like texture forms
Then, add the buttermilk mixture, using a spatula or fork gently mix until all the buttermilk is combined. If the mixture is still a little dry, add another tablespoon of milk until all the flour is absorbed.
Turn the dough out onto a lightly floured work surface. Using a rolling pin, gently roll the dough into a 1½-inch thick rectangle. Fold the dough in half on top of itself and roll it down into another 1½-inch thick rectangle. Repeat the folding process about 4 times. Then press the dough down into a 1-inch thick rectangle.
Use a biscuit cutter, cut out the biscuits, pressing it straight down into the dough (be careful not to twist). Once you've cut out as many biscuits as you can, gather the scraps and pat the dough out to 1-inch thickness a second and third time to finish cutting out all of the biscuits. Place them on the prepared baking sheet.
Place the biscuits on the prepared baking sheet and brush with a little milk or melted butter.
Bake for 13- 15 minutes, turning half way or until the tops are lightly golden brown.
Serve with a little jam, butter, maple butter and some love! Enjoy!:)
