Blueberry Scones

These are always a big hit every time I make them. They are from America's Test Kitchen and turn out wonderful every time!

It is important to work the dough as little as possible—work quickly and knead and fold the dough only the number of times called for. The butter should be frozen solid before grating. In hot or humid environments, chill the flour mixture and workbowls before use. If fresh berries are unavailable, an equal amount of frozen berries (do not defrost) can be substituted. An equal amount of raspberries, blackberries, or strawberries can be used in place of the blueberries. Cut larger berries into 1/4- to 1/2-inch pieces before incorporating. Refrigerate or freeze leftover scones, wrapped in foil, in an airtight container. To serve, remove foil and place scones on a baking sheet in a 375-degree F oven. Heat until warmed through and re-crisped, 8 to 10 minutes if refrigerated, 16 to 20 minutes if frozen. See final step for information on making the scone dough in advance.

Ingredients:

8 tablespoons (4 oz. / 113g) unsalted butter (1 stick), frozen whole (see note above)
2 (1 oz./ 28g) tablespoons butter - melted
1 1/2 cups fresh blueberries (about 7 1/2 ounces), picked over (see note above)
1/2 cup (4 oz./ 120 ml) whole milk
1/2 cup (4oz) sour cream
2 cups unbleached all-purpose flour (10 ounces), plus additional for work surface
1/2 cup sugar (3 1/2 ounces), plus 1 tablespoon for sprinkling*
2 teaspoons baking powder
1/4 teaspoon baking soda
1/2 teaspoon table salt
1 teaspoon grated lemon zest

1. Adjust oven rack to middle position and heat oven to 425 degrees F. Grate frozen butter on large holes of box grater (you should grate total of 8 tablespoons). Place grated butter in freezer until needed. Melt 2 tablespoons of 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 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. Following illustrations, fold dough into thirds like a business letter, using bench scraper or metal spatula 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 from one end to the other, 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.

To Make Ahead: After placing the scones on the baking sheet, either refrigerate them overnight or freeze. When ready to bake, for refrigerated scones, heat oven to 425 F degrees and follow directions in step 6. For frozen scones, heat oven to 375 F degrees, follow directions in step 6, and extend cooking time to 25 to 30 minutes.

*I used one tablespoon of turbinado sugar for the last step instead of 1 tablespoon regular sugar.
