Toast whole sesame seeds and whole sumac berries in a hot pan until fragrant, shaking often. Cool and grind. Mix with the remaining ingredients. Seal in a tight jar and keep in a dark cupboard.
This spice blend may be left “chunky” or ground finely as you desire. Do watch the sumac berries; they can be very hard and need to be broken down so there is no danger of injuring a tooth.
