21. Potatoes

Potatoes taste best when stored in a dry, cool area. They should also remain unwashed until you’re ready to use them. Refrigerator temperatures will cause the starches to break down, causing the potatoes to taste gritty and even sweet. If the potatoes have been refrigerated the skins may darken prematurely during the cooking process.
20. Pickles

Most pickles are refrigerated, but really don’t need to be. The way most pickles are made, including the high salt content, makes it unnecessary to keep them at refrigerated temperatures. In fact, pickling is often used as a food preservation method.
