Prisonchef gave great advice. These health dept’s can drive you nuts or to the poor house.
As for the oil, I use a zero-trans fat canola oil. More money to be sure but I cange it out less. But the MAIN reason I do it is because my fries are fresh kennebec’s and the canola oil gives them the crispest cleanest flavor. Also very little cross over flavor from different food items.
