Work in the butter using a pastry cutter or fork until the mixture resembles coarse meal with some larger pieces remaining.
½ cup (114g) cold unsalted butter
Stir in the chopped bacon, grated cheese, and jalapeño or chives if using.
1 cup cheddar cheese, ¾ cup cooked bacon, ¼ cup jalapeno peppers or chives
Whisk together the buttermilk and egg in a measuring cup.
¾ cup (180ml) cold buttermilk, 1 large egg
Pour the wet ingredients over the dry ingredients and mix until the dough comes together.
Scrape the dough onto a floured surface. With floured hands, gently knead the dough into a shaggy ball.
Flatten and shape into a 6″ circle and cut into 8 wedges.
Transfer onto a parchment paper-lined baking sheet and chill in the fridge for 20 minutes.
Brush the surface with more buttermilk. Bake at 400F for 20-25 minutes or until golden brown.
