Add sugar, water, and sumac powder to a small saucepan and bring to a boil over medium heat. Boil for 5 minutes then simmer over low heat for another 5 minutes.
Once the syrup is cool, strain through a soup bag and into an 8-ounce canning jar. Discard the solids.

Sumac Cranberry American Mule
Fill a Moscow Mule mug with one cup of crushed ice, then add rum, cranberry juice, and sumac syrup. Top with ginger beer.
Virgin Sumac Cranberry Mule
Follow the recipe steps above but leave out the alcohol and top with 6 to 8 ounces of ginger beer.
Garnish And Serve
Garnish with a lime wheel or wedge. Toss a handful of cranberries into the mug, or skewer them onto a toothpick. Finish by adding a sprig of mint or rosemary and serve immediately.
Notes
Be sure to strain the Sumac Syrup through a soup bag so that the syrup does not have a grainy texture. Additionally, resist the temptation to squeeze the bag to get every last drop. Doing so will result in a cloudy syrup.
Some people prefer their Moscow Mule shaken, not stirred. To do so, add ice, alcohol, cranberry juice, and sumac syrup into a cocktail shaker(affiliate link) and shake vigorously until mixed and chilled. Next, strain the drink into a copper mug filled with crushed ice. Top with ginger beer, stir, garnish, and serve.
Between vodka and rum, I highly recommend using rum. However, not just any rum. Appleton Estate Signature Jamaica Rum tastes amazing in this cocktail!
