Gum syrup, or jarabe de goma, is made by dissolving 1 cup of sugar in 1/2 cup of water over medium heat, whisking in 1 tablespoon of powdered gum arabic, and simmering gently for about 10 minutes until slightly thickened, then cooling and storing it in a sterilized jar in the refrigerator. It takes 5 minutes of preparation plus 15 minutes of cooking and makes 12 servings.
Unlike simple syrup, it gives cocktails a silky texture and more body, which is why it is a favorite for pisco sours and daiquiris.
How to Make Gum Syrup?
With just three ingredients, sugar, water, and powdered gum arabic, you get a syrup that balances sour flavors with a silkier sweetness.

Additional Tips

Sprinkle the gum slowly
Adding the gum arabic gradually while stirring prevents lumps.

Yes, to sweeten, but you lose the texture and body that gum arabic adds.
3. Where can I buy gum arabic?
In baking supply shops, cocktail supply stores, or herbal shops; always choose a fine powder.
4. How do I use it in a pisco sour?
Use it in place of sugar or simple syrup in the same amount; it also helps build the foam.
