1
Affix your frying thermometer to a Dutch oven or another deep, heavy frying pan.
-
2
Add enough oil so that the pan is just under half full (for me, 2 quarts is perfect).
-
3
Turn heat to medium-high and heat oil to 325F to 350F.
-
4
Set up a draining station by getting out a jelly roll pan or any cookie sheet with sides.
-
5
Line with paper towels or newspaper, then put an inverted cooling rack on top of the paper.
-
6
Also, get out a large bowl in which to store the chips.
-
7
Line this bowl with one sheet of paper towel.
-
8
While the oil is heating, scrub the potatoes and dry well.
-
9
With a mandoline slicer, slice potatoes very, very thinly.
-
10

-
11
For best results, fry a few test slices first to make sure the chips will be crispy.
-
12
If theyre too thick, your chips will be soggy and chewy.
-
13
After the potatoes are sliced, fry in batches, being sure to keep the oil between 325F and 350F.
-
14
Youll know the batch is done when the chips are golden brown and the frying oil is no longer bubbling violently.
-
15
Remove each batch from the oil with a wok skimmer (a small basket with a long handle), or a slotted spoon will work in a pinch.
-
16
Transfer to the draining station.
-
17
Sprinkle the chips with salt while theyre still hot.
-
18
Repeat this process, pausing every so often to transfer cooled potato chips from the draining rack to the bowl.
