A fine white powder derived from the hardened sap of the acacia tree.
Gum (or Gomme) Syrup is a basic rich simple syrup thickened with gum arabic. Gum syrup adds a silky rich texture to cocktails. Use Jeffrey Morgenthaler's recipe below:
12 oz. superfine sugar
6 oz. water, divided into 2-oz. and 4-oz. portions
2 oz. gum arabic/gum acacia
In a small plastic container, combine gum arabic and 2 oz water. Stir with a chopstick to combine, then cover. Let sit for 48 hours, or until the gum arabic has been completely dissolved by the water.
In a small saucepan, combine sugar and remaining 4 oz water. Heat gently until sugar begins to dissolve, then fold in the gum arabic mixture. Remove from heat immediately, let cool and bottle in a plastic squeeze bottle. Keep refrigerated for up to 1 month.
