In a large mixing bowl combine the flour, baking soda, baking powder & salt
Make a well in the center & add olive oil, sour cream & beer
Stir with a wooden spoon until the dough comes together
Transfer to a floured surface re-coating hands with flour as needed (it will be quite sticky at first)
Knead about 4-6 minutes
Cut into 8 even sections & form into balls
Cover & let rest about 10 minutes
Press balls flat & cook in a large skillet until lightly browned on both sides
(You will know they are cooked through when they sound hollow when tapped with your fingernail in the center of the disk)
Cooking should take about 3 minutes per side
Serve warm & coated with melted butter
