Za’atar is the Arabic word for wild thyme, and for the spice mix made with the herb, roasted sesame seeds and the ground sour red berries of the sumac tree. It is dearly beloved in the Middle East, where it is eaten virtually daily, sprinkled on dishes as a garnish, or mixed with olive oil to make a paste. Greg always has a little jar of it in the fridge, which he eats on toast for breakfast instead of Vegemite!
