I used 4 large potatoes. Feel free to leave the skin on if you prefer. Fill a large pot or Dutch oven with peanut oil {or canola oil}, and add the potatoes slices.
Turn the heat up to HIGH and add your candy thermometer to the edge of the pot. Do not allow the temperature to go above 350 degrees, turn down the heat if you need to.
Cook, stirring occasionally until they are crispy and golden brown. Remove from oil with a slotted spoon or tongs and place on several layers of paper towels to drain.
Sprinkle with sea salt or seasonings of your choice and serve.
Notes
The oil is not calculated in the Nutrition Facts because 1) you do not consume all of the oil 2) there is no way to calculate exactly how much oil is absorbed by the potatoes.
