Nearly everyone likes potatoes. They are economical, low in calories, and nutritious. They can be prepared in a variety of ways. The four basic types of potatoes are round whites, long whites, russets, and round reds. There are also many specialty potatoes, including blue-fleshed, red-fleshed, yellow-fleshed, and fingerling. Maine- grown potatoes are available late July through the following May.

Nutrition Information

Potatoes are a good source of vitamin C and potassium. Unfortunately, they have been accused for many years of being a high-calorie food. This is unfair: one medium baked potato contains only about 110 calories. But beware! If you add one tablespoon each of sour cream and butter or margarine, the calories jump to 240!

Selection

Look for plump, firm, unbruised potatoes. Avoid those that are green or have started to shrivel or sprout.

Storage

Store potatoes in a cool, dry, dark place that is well ventilated. A temperature of 45 degrees F is best for storage. Potatoes stored above 45 degrees F will sprout and shrivel. Those stored below 45 degrees F will develop a sweet taste, as some of the potato starch turns to sugar. This increase in sugar will cause the potato to darken when cooked. Do not store potatoes in the refrigerator.

Preparation

Scrub potatoes well if they are not peeled. Be aware that peeled potatoes will turn dark if they are not cooked soon. Do not soak them in cold water to keep them white. This will cause the potatoes to lose vitamins.

Boiling: Best for thin-skinned potatoes. Cover potatoes with water in a saucepan with a tight-fitting lid. Bring to a boil and cook covered. Medium potatoes will take about 30 to 40 minutes to cook.

Baking: Best for thick-skinned potatoes. Bake potatoes 45 minutes at 400 degrees F, or bake them along with whatever you have in the oven and adjust the time according to the temperature. It can range from 325 to 450 degrees F. At higher temperatures, the skin will be crisper. Pierce skin with a fork so steam will escape. This keeps the potato from bursting.

Microwaving: Pierce skin with a fork in a few places. Arrange potatoes on a paper towel, one inch apart. Microwave on high power for four to six minutes per potato. Turn potatoes over after half the cooking time. When they are done, take them out and let them stand for five minutes. This allows the potatoes to finish cooking with their own trapped steam.

Steaming: Best for thin-skinned, small potatoes. Cut a small strip from the potato. This will keep the skin from breaking. To steam, bring one inch of water to boil in the bottom of a pan. Place a colander or a collapsible steaming basket in the pan. Then put the vegetables in the colander or steamer and cover it tightly. Reduce heat to medium-low, but make sure it is high enough to keep the water bubbling. Steam for 15 to 20 minutes.
