1/2 c. sour cream
2 c. flour, plus extra for the work surface

*Please don't be afraid of this recipe! It is easier than is sounds!
Preheat oven to 425 degr. Place rack in middle position of oven.
Grate 8 tbsp. frozen butter into medium size bowl and return to freezer. Place blueberries into freezer until needed. Whisk milk and sour cream together and return to fridge.
Whisk dry ingr. in large bowl. Add frozen grated butter and toss with your fingers until evenly coated. Add milk mixture to flour mixture; fold with a rubber spatula until just combined. Using the spatula, transfer the dough to a liberally floured work surface. Dust the surface with flour. With floured hand, knead dough 6-8 times until it just holds together in a ragged ball, adding flour as needed to prevent sticking.
Roll out dough into 12 in. square. Fold into 3rds like you were folding a business letter using a scrapper to release dough from surface. Lift short ends and fold into thirds to form a 4 in. square. Cover with cloth and let rest in freezer for 5 min.
Transfer dough to floured surface and roll into 12 in. square. Sprinkle blueberries onto surface and press into dough. Roll dough jelly roll style. Lay log seam side down and with your hands, press log flat, to 4 in. wide. You will have a 4 in. by 12 in. rectangle. Cut into 4 squares. Then cut diagonally each square to make 8 triangles. (you may add an additional diagonal cut to X the square, thus 16 triangles.) Brush tops with remaining butter, (melted), sprinkle with sugar.
Transfer to parchment cover baking sheet. Bake 18-25 min. until golden brown.
