The baking time for a potato depends upon the manner in which it's prepared, and typically takes an hour if baked in an oven preheated to 425 degrees and 90 minutes when wrapped in foil and immersed in hot charcoals. Microwave a potato on high for 10 to 15 minutes.
Russet potatoes, also called chef's potatoes and Idaho potatoes, have thick brown skin and starchy white flesh, and are the most commonly used potato for baking. Sweet potatoes feature moist orange skin and vitamins A and C, though they aren't part of the potato family. Potatoes are among the world's top four produced crops.
