Preheat your oven to 425 F.

Whisk together flour, salt, baking powder and baking soda. Cut the butter into the flour using a pastry cutter, fork or even by hand until mixture resembles wet sand. Stir in the grated cheese and chives. Then slowly add as much sourdough starter (or buttermilk) as needed until a soft dough forms. Turn out dough onto a floured surface and knead over a couple of times.

Flatten the dough and cut into 10-12 biscuits (using a knife or biscuit cutter). Place biscuits on a lined baking sheet and bake for 12-15 minutes until golden.
