Zaatar Mix

1 cup sumac
2 cups roasted, ground sesame seeds
1/2 cup dried ground thyme
2 tablespoons dried leaf oregano
2 tablespoons dried leaf marjoram
2 tablespoons dried leaf savory
1 tablespoon salt, or to taste (optional)

Mix all the ingredients together except the salt (some sumac is
salty; also, you may not want the salt for some zaatar uses). Taste
carefully and add the salt if desired. Keep the zaatar mix in a
tightly closed jar (the sesame seeds will last 6 months maximum);
it will stay fresher in the refrigerator or freezer than at room
temperature.
