Are purple potatoes refrigerated or frozen in the refrigerator?
Just refrigerate it. For cooked purple potatoes, you can keep them in the refrigerator for 2 to 3 days. Seal the purple potato while it is hot. If it is raw purple potato, it can be preserved for a long time, because raw purple potato can be preserved in the refrigerator for several months as long as it does not go bad. It's best not to leave it for too long.
