Dry sage refers to the dried leaves of the sage plant, or Salvia officinalis as it is scientifically known. Dried rubbed sage refers to the whole or slightly crumbled leaves of the plant, while ground sage is finely ground dried sage leaves.
Dried rubbed sage is preferable over ground sage, as it stays fresh for longer than the ground variety. Dried sage can be found in the spice or bulk section of grocery stores and specialty stores. It can be stored in a cool, dry location for up to six months. Fresh sage can easily be dried in a dehydrator or air-dried at home for later use.
