How do I store purple potatoes to keep the skin fresh?
To keep the skin on purple potatoes fresh, it is essential to store them properly. Purple potatoes should be stored in a cool, dark place, away from direct sunlight and heat. A temperature range of 40-50°F (4-10°C) is ideal for storing potatoes. You can store them in a paper bag or a breathable container, such as a mesh bag or a ventilated box.
