The qualities can vary from tasteless ground straw (and/or with unknown fillings) to a fresh and savory blend with genuine mainstay ingredients. Look for transparent and specific ingredients. Avoid brands with unspecific listed ingredients such as “spices” or “middle easter spices” or a generic “zaatar” in the ingredient list. In general, the better qualities cost twice to four times the price of the fake zaatar mixes. We of course invite you to try Tyme Foods' classic zaatar blend which we believe will raise your expectations on zaatar taste and nutritious ingredients.
