An ingredient commonly used in mixed drinks. Like bar syrups, it is a sugar and water mixture, but has an added ingredient of gum arabic which acts as an emulsifier. Gomme syrup is made with the highest percentage of sugar to water possible, while the gum arabic prevents the sugar from crystallizing and adds a smooth texture.
Recipe: Slowly add 2 oz [57g] of gum arabic into 2 oz of near boiling distilled water, stir constantly. Allow it to sit a day or two, until dissolved and cool. Then separately, add 8 oz of sugar into 4 oz of water, bring to a boil and stir until dissolved. Add dissolved gum and boil for 2 more minutes, skim off the foam. Allow to cool, filter through a cheesecloth and bottle. It will keep unrefrigerated.
