Also known by its French spelling, gomme, gum syrup is a sugar syrup with gum arabic, a resin from the Acacia tree, incorporated into it. Gum syrup fell out of favour with bartenders because it is difficult to make, and a straight simple syrup is both easier and cheaper. However, where both syrups add sweetness, gum syrup adds viscosity as well, giving a richer mouthfeel and weightier texture to cocktails. Organic cane sugar gives the syrup an amber colour and a light molasses flavour. It is best used in aromatic, spirit-forward cocktails such as Sazeracs, Old-Fashioneds and Juleps.
