Preparation If using fresh za’atar or oregano, arrange it on a towel-lined plate and microwave in 15-second intervals, stirring between intervals, until dry and crumbly, 2 to 2 1/2 minutes. Crumble the leaves by hand or in a spice grinder until almost fine (the way dried herbs look), then combine in a medium bowl with the marjoram, sesame seeds, thyme, sumac, and salt. Store in an airtight container for up to 3 months. Reprinted from Sababa by arrangement with Avery, an imprint of Penguin Publishing Group, a division of Penguin Random House LLC.
