Like, seriously, the world's best. Biscuit doughs tend to be tricky. Thusly, if you follow these golden rules of biscuit making, you will be revered:
1.Butter must be cold, ice cold. Actually, all ingredients, dry and wet, and even mixing bowls should be kept chilled.
2.Butter must be evenly distributed throughout the dry ingredients before the wet ones are added.
3.Dough should be worked as little as possible.
It's not as easy as it sounds if you do not have the proper equipment. You'll need:
plenty of countertop space
dough cutter/bench scraper
Be like a true Brit and slather scones with clotted cream and blackberry jam.

makes 8 scones
8 Tbsp unsalted butter, frozen solid, plus additional 2 Tbsp, melted for brushing
1 1/2 cup fresh blueberries
1/2 cup whole milk
1/2 cup sour cream
2 cups all-purpose flour
1/2 cup sugar, plus extra for sprinkling
2 tsp baking powder
1/4 tsp baking soda
1/2 tsp salt
1 tsp lemon zest
1. Adjust oven rack to middle position and heat oven to 425 degrees. With the large holes on a box grater, grate the 8 tablespoons of frozen butter. Place grated butter in freezer until needed. Melt 2 tablespoons of remaining ungrated butter and set aside. Place blueberries in freezer until needed.
2. Whisk together milk and sour cream in medium bowl; refrigerate until needed. Whisk flour, 1/2 cup sugar, baking powder, baking soda, salt, and lemon zest in chilled medium bowl. Add frozen butter to flour mixture and toss with fingers until thoroughly coated.
3. Add milk mixture to flour mixture; fold with spatula until just combined. With rubber spatula, transfer dough to liberally floured work surface. Dust surface of dough with flour; with floured hands, knead dough 6 to 8 times, until it just holds together in ragged ball, adding flour as needed to prevent sticking.
4. Roll dough into approximate 12-inch square. Fold dough into thirds like a business letter, using bench scraper to release dough if it sticks to countertop. Lift short ends of dough and fold into thirds again to form approximate 4-inch square. Transfer dough to plate lightly dusted with flour and chill in freezer 5 minutes.
5. Transfer dough to floured work surface and roll into approximate 12-inch square again. Sprinkle blueberries evenly over surface of dough, then press down so they are slightly embedded in dough. Using bench scraper or thin metal spatula, loosen dough from work surface. Roll dough, pressing to form tight log. Lay seam-side down and press log into 12 by 4-inch rectangle. Using sharp, floured knife, cut rectangle crosswise into 4 equal rectangles. Cut each rectangle diagonally to form 2 triangles and transfer to parchment-lined baking sheet.
6. Brush tops with melted butter and sprinkle with remaining tablespoon sugar. Bake until tops and bottoms are golden brown, 18 to 25 minutes. Transfer to wire rack and let cool 10 minutes before serving.
