Sour Cream and Chive Biscuits

Gather the ingredients.

Grease a 9 x 9-inch square pan with nonstick cooking spray or softened butter. Line the bottom with parchment paper

In the bowl of a food processor fitted with a metal blade, process the all-purpose flour, baking powder, baking soda, salt, and pepper.

Add the cold butter and chives to the bowl, then pulse until the mixture resembles coarse meal.

Transfer the mixture to a large bowl. Add the sour cream, then use a wooden spoon to combine until a shaggy dough forms. (This will take awhile. You can use your hands to knead the dough together in the bowl, if desired.)

Transfer the dough to a work surface (no need to flour it, but if you find the dough is too sticky, a little flour will help). Knead the dough a few times until it is no longer crumbly and the dry bits are fully integrated. It may seem like this will never happen, but it will. Be patient!

Gently pat or roll the dough into a rectangle at least 1 1/2 inches thick to ensure a tall biscuit.

Using a 3-inch biscuit or cookie cutter dipped in flour, cut out the biscuits from the dough. Place in the prepared pan so they are touching (this helps them rise).

Collect any scraps and re-roll, then cut as needed. (Note, the biscuits made from scraps will not be as flaky and tender.)

Tightly wrap the pan in plastic wrap and freeze the biscuits for at least 2 hours. Preheat the oven to 400 F.

To make the egg wash, whisk the egg and salt in a small bowl

Once the biscuits are frozen, brush the wash over the tops of each.

Bake for about 30 to 35 minutes or until the biscuits are golden brown on top and lightly browned on the bottom, rotating the pan halfway through. Let the biscuits sit 1 or 2 minutes in the pan until they are easy to handle.

Biscuits are best eaten the day they are made (slathered in salted butter), but can be stored, tightly wrapped in plastic wrap, at room temperature for up to three days.
