Heat a large skillet or tabletop glass-ceramic grill over medium-high heat (for the LeMax, preheat at level 9 for 5 minutes, then reduce heat to 8).
NOTE: for the stovetop method, two skillets is best, since you will get better results if every potato is in contact with the bottom of the pan. This will guarantee that they get crispy. A heavy-bottomed or cast-iron skillets is the best choice. Stainless steel and ceramic are also good options.
Lightly grease the surface with clarified butter (about 1 teaspoon, or more).
