Are you simmering or boiling? Many recipes will instruct you to bring a liquid (usually water) to a boil and then reduce heat to simmer. The main reason for this method is to compensate for the drop in temperature when food is added. While both techniques are very similar and may be used in the same recipe their effect on foods are very different.

Simmering or a "gentle boil" happens at temperatures between 185 degrees and 205 degrees Fahrenheit. This method of cooking allows meats and other foods more time to cook without overcooking. You'll recognize the simmer by the occasional small bubbles that rise to the center. Simmering requires less energy from your appliances and keeps many proteins from becoming tough.

Boiling is reserved for liquids, typically water, at the temperature of 212 degrees. Once a liquid reaches a higher temperature, it's transformed into steam. You'll recognize it by the rapid, rolling, large bubbles rising to the surface. Boiling may be used on green vegetables to cook them quickly and keep their texture and color. It may also be used to keep foods like pasta moving quickly so it doesn't stick together or get soggy. Boiling may also be used to reduce sauces.
