Boiling is cooking in water at a temperature of 212 degrees. This is done on the open burners on top of the range. There are three sizes of burners: the giant, the ordinary and the simmerer. In bringing water to boil quickly use the giant burner, then continue boiling on the simmerer or one of the ordinary burners turned low. Do not waste gas by boiling hard. Use covers on kettles.

Green vegetables when boiling retain their color better if the lid is left off the pot.
