• Peel the potato and run through a mandoline at 1/8 inch thickness.
• Add the vinegar to a medium bowl and put the potato slices in the vinegar. Let it sit 15-30 minutes.
• Place the potato slices on a clean towel or paper towel. Also, dab the top of the potato slices to dry them off.

For the air fryer:

• Add the potato slices to the air fryer basket in a single layer. (I had to do two batches.) Spray the potatoes with olive oil spray and sea salt.
• Cook at 350 degrees for 10 minutes, flipping halfway through.

For the oven:

• Preheat oven to 375 degrees F.
• Line a baking sheet with parchment paper. Add the potato slices in a single layer. Spray with olive oil and add the sea salt.
• Bake for 20 minutes, flipping halfway through.
