Lavender


I encountered this recipe in _A Book of Pot-Pourri_ by Gail Duff.

        Dissolve 1 tablespoon saltpeter in 1 cup warm water.  Soak dried
        stems of lavender (flowers removed for other uses) in the
        solution for 30 minutes, then dry completely.  Once dried, they
        may be stuck into a container of dry sand and burned like stick
        incense.
