Cook at 300 degrees until potatoes are limp. Remove basket from grease and let potatoes drain and cool in basket while heating fryer oil to 350 degrees. When oil is ready, submerge basket of potatoes. Fries will start to rise to top of basket and at this point use a long handled spoon, spatula, fork etc. (make sure it’s suitable for hot oil!) to gently stir fries to separate while continuing to cook until golden brown. (Time depends on how big you slice up potatoes).
