All versions of the spice mix contain an almost even mixture of thyme, rosemary, savory and oregano, but other variations include marjoram, lavender, tarragon, fennel seeds, bay leaf powder, basil and chervil. To create a common blend from scratch, simply mix ½ tsp. thyme, 1 tsp. rosemary, 1 tsp. savory, 1 tsp. oregano, 1 tsp. marjoram and 1 tsp. chopped, dried lavender flowers.
