Because I've been trying all my life to make nice biscuits and I was too much of a moron, until I discovered this recipe. It has egg and cream of tartar, which is weird, but they come out great every time. Flaky little crust, lovely, lofty insides, rich, buttery taste.
Preheat oven to 450.
In a bowl, combine the flour, sugar, salt, baking powder, and cream of tartar.
Grate the chilled butter with a box grater into the dry ingredients.
Stir in the milk and egg and mix until just combined. Don't overwork it. It's fine to see little bits of butter.
On a floured surface, knead the dough 10-15 times. If it's very sticky, add a little flour.
With your hands, press the dough out until it's about an inch thick. Cut biscuits. Depending on the size, you can probably get 20 medium-sized biscuits with this recipe.
Grease a pan and bake for 10-15 minutes or until tops are golden brown.
