These biscuits are amazing! I switch up the cheese depending on what I am serving them with. The recipe is adapted from Bon Appetite Feb 2010.
3 3/4 c flour
1 1/2 TBSP baking powder
1 1/2 tsp baking soda
1 1/4 tsp salt
1/2 c chilled unsalted butter, cut into cubes
2 c grated sharp cheddar cheese
1/3 c chopped fresh chives
1 3/4 c chilled buttermilk
Preheat to 425°F. Line heavy large baking sheet with parchment paper.
Combine flour, baking powder, baking soda, and salt in processor; blend 5 seconds. Add butter cubes. Blend until coarse meal forms, about 30 seconds. Transfer flour mixture to large bowl. Add cheddar cheese and fresh chives toss to blend. Gradually add buttermilk, stirring to moisten evenly (batter will feel sticky).
Using lightly floured hands, drop generous 1/2 c batter for each biscuit onto prepared baking sheet, spacing batter mounds about 2 inches apart.
Bake biscuits until golden and tester inserted into center comes out clean, 18 to 20 minutes.
