I adapted this and several other recipes in this section from ones by Khanum-e Razavi, a great cook from Mashhad. Whole golpar/Persian hogweed seeds, shown on the right in the photo on the facing page, are not available in the U.S., but you can find ready-ground golpar in Iranian stores, sometimes under the name golpar/angelica. I was surprised by the inclusion of sumac in this mix, but it works very well, especially for soups and meatballs.
