In a food processor or spice grinder, combine all spices and blend until fine. About 30 seconds. Remove and set aside.
With a mandoline or extremely good knife skills, thinly slice the potato to about 1/10 inch thick. (2.5mm)
Put the potato slices in a bowl of cold water. The potatoes should be submerged. Soak 30 minutes. Wash potatoes in water until no longer cloudy. About 3 to 5 washes. Drain water.
In a pot large enough to hold slices, fill with water and bring to a boil. Add vinegar and 1 tsp salt to water and parboil potatoes. 3 to 5 minutes. Slices will curl up. Remove to a tea towel lined sheet pan and dry thoroughly. This will remove more starch from the chips and make them crunchy.
In a cast iron pan or dutch oven, heat oil to 375 degrees. Add dried potato slices in small batches and fry, stirring constantly and flipping frequently. Potatoes will turn brown and crispy. 3 to 5 minutes. Keeping an eye on the oil temperature, not letting it drop too low, adjusting burner accordingly.
Remove with a spider or wire skimmer to a paper towel lined basket. Season immediately with BBQ seasoning. Let cool
Chips will store in an airtight container for 1 week. Good luck with that.
