Simmer is a term used when something is to be cooked over a very low heat, generally for an extended amount of time. Normally, you bring something just to a boil and then turn down the heat to low (or possibly medium low) so that it continues to simmer. The term simmer is only used when there is liquid involved in your recipe. Simmer is most often used for making some type of homemade sauce or stew.
