I've been making this recipe for a while now and it isn't the best I've ever had, but it is the best I've been able to make so far. They always get great reviews from guests when I make them.
I always cut the butter up into small pieces and throw it in the freezer for 10 minutes or so to get it really cold.
From here: http://www.foodnetwork.com/recipes/food-network-kitchens/white-sausage-gravy-recipe/index.html
2 cups all-purpose flour (about 8 ounces), plus more for dusting
1 tablespoon baking powder
1 teaspoon sugar
1 teaspoon fine salt
7 tablespoons cold unsalted butter, sliced
3/4 cup milk
1 tablespoon heavy cream
1 tablespoon unsalted butter, melted
To make the biscuits: Place a rack in the center of the oven and preheat to 450 degrees F. Line a baking sheet with two layers of parchment paper. Set aside.
In a large bowl, whisk together the flour, baking powder, sugar, and salt. Rub 2 tablespoons of the butter into the flour with your fingertips until completely absorbed. Work the remaining butter into the flour until it is in even pieces about the size of a pea. Gently stir the milk into the flour mixture to make a loose dough.
Lightly dust a clean work surface with flour and turn the dough out onto it. Pat the dough into a 1/2-inch thick rectangle. Fold the dough in thirds like a business letter. (For a flakier biscuit repeat the folding a second time.) Pat the dough into a 5 by 8-inch rectangle about 3/4-inch thick. Use a 2- to 3-inch round cutter to make 6 biscuits, and transfer them to the prepared baking sheet. Press together the scraps of dough and cut 2 more biscuits.
To make the glaze: Mix the cream and melted butter together in a small bowl. Lightly brush the tops of the biscuits with the glaze. Bake until lightly browned, about 15 minutes. Cool on a rack for 5 minutes before serving.
Yield: 8 biscuits
