Mix ingredients together using a pastry cutter or fork, adding the ACV at the end (final mixture should adhere and not be crumbly but also not sticky).
Roll out and cut biscuit shapes (or just shape free form) onto parchment-lined baking tray.
Bake at 375 degrees Fahrenheit for 30-35 minutes or until biscuits are browned, and firm in the middle.
Sprinkle with rosemary and enjoy!
