The sweet, milky honey (angobīn) found on the Gaz plant is associated with manna, a food mentioned in the religious texts of the Abrahamic religions.Although originally believed to be sap manufactured by the Tamarisk tree, the sticky white substance was found to be formed from honeydew, which is exuded from the anus of the nymph of a psyllid insect, either Cyamophila astragalicola or C. dicora, in its final instar, which live on plants of Astragalus adscendens, and is collected annually and is combined with other ingredients including pistachio or almond kernels, rosewater and egg white. Modern versions of gaz may use sugar and corn syrup as substitutes for psyllid manna.
