Potatoes must be peeled to be pressure canned, frozen or dried.

You can store your small potatoes at room temperature for 1 to 2 months, unwashed, in a cool, dry, well-ventilated area away from light, which causes greening.

Washed or unwashed potatoes can be stored in the refrigerator for 1 to 2 weeks. This can reduce sprouting. However, starches will turn to sugar (causing fried potatoes to darken.)
