Article: You can find purple potatoes at most grocery stores, typically near other fingerling potatoes. Look for potatoes with a deep, true purple hue and without deep scars. Be sure to avoid potatoes with a greenish tinge, as they can taste bitter and even lead to digestive issues. Avoid placing your potatoes in the refrigerator, as this can affect their taste and color. Instead, choose a cool, dark, and dry place, like a pantry, to keep your potatoes. If you want to bag them, use a paper bag rather than a plastic one. If you can store the potatoes in an area that’s 45 to 50 °F (7 to 10 °C), such as a basement, they’ll stay fresh for up to several weeks. Although they taste great when cooked together, potatoes and onions should be stored separately. When raw, both onions and potatoes release gases and moisture, which can cause the other to go bad more quickly. Keep them at least a few feet apart in your kitchen. Place the potatoes in the sink and cover them with water. Let them sit for about 20 minutes, then drain the sink and rinse again before scrubbing. A lot of the dirt will fall away while soaking, which will save you scrubbing time. This is a great technique if you’re washing a large amount of potatoes all at once. Take one potato at a time and wash it under cool, running water. Scrub the surface well using a brush or your hands, but don’t use soap. To keep your potatoes fresh for longer, wait to wash until you’re ready to use them.

What is a summary?
Buy potatoes that are unblemished with a deep purple hue. Store purple potatoes in a paper bag in a cool, dry place for up to a week. Store purple potatoes away from onions. Soak the potatoes before scrubbing to save time. Scrub potatoes under running water to clean them.
