Potato Food Facts
Potatoes are available all year. Potatoes should be smooth and well shaped, and not bruised. Do not buy if they have sprouted or have a green tint to the skin (this indicates high solanine content). Store at room temperature in a dark area and do not refrigerate. Refrigeration may turn a percentage of the starch into sugar. Keep away from heat or cold.
Sweet Potatoes/Yams
Sweet potatoes and yams are available all year. The skin should be uniformly copper or light tan-colored. Do not purchase if they have white areas or are damaged; this probably means decay. Store in a cool, dry place and do not refrigerate.
