There were a couple methods out there for making the gomme, but for sake of time, I chose the most rapid method via A Mountain of Crushed Ice.
4 tablespoons gum arabica powder (or acacia powder)
2 ounces hot water
Heat water to just about boiling (I used an electric water kettle) and slowly mix into the powder in a heat-proof bowl. Then stir to combine, pushing clumps of powder into the side of the bowl to break it up. Let the mixture absorb for 20 minutes and then briskly stir again. Repeat process until all the powder is dissolved (this took about an hour for me).
Next, make a pineapple syrup. Unlike my other syrups, this will be a 2:1 ratio, or a rich syrup.
2 cups sugar
1 cup water
1 cup pineapple chunks, plus 2 tablespoons juice
In a medium sauce pan over medium-high heat, combine sugar and water. Stir until dissolved and add pineapple chunks and juice. Bring to a boil and immediately remove from heat. Cover and let sit two hours (if you desire a stronger pineapple flavor, let it sit up to 4). Strain pineapple chunks (use them for garnishes or to top some pancakes). Add gomme and stir to combine. Bottle in an airtight container. Total mixture yields about 2-1/2 cups.
Now at this point you can pat yourself on the back and stare at your freshly made bottle of pineapple gomme syrup and then exclaim, NOW WHAT? Put it in a cocktail!
Pineapple gomme syrup seems to be most commonly used in the Pisco Punch. So start there if this is all new to you. If you’ve covered this base already, please feel free to share what you use it in.
2 ounces pisco, Campo de Encanto used here
1/2 ounce pineapple gomme syrup (recipe above)
3/4 ounce freshly squeezed lemon juice
pineapple chunk and sprig of mint for garnish
In a shaker 2/3 filled with ice, add all ingredients and shake well about 20 seconds. Strain into a chilled cocktail coupe. Garnish with a pineapple chunk (those sugared leftovers are perfect here) and a sprig of mint.
Since we’re using a rich syrup here, I cut the amount back from the original recipe by a 1/4 ounce. I found the drink a touch too sweet on the first try. By doing this, the fruitiness of the pisco comes through a bit more with hints of peach and citrus. The lemon juice gives a pleasant bite that contrasts nicely with the sweetness. Overall, super smooth (thanks gomme!) and an easy sipper.
