3 1/2 cups waterIn a large saucepan over high heat bring water just to a boil. Remove from heat, stir in dried lavender flowers, and let steep for at least 20 minutes, or even overnight. Strain mixture into a deep saucepan, discarding the lavender flowers. Add lemon juice and pectin and stir till dissolved.
