You may have had grenadine before. It’s a pretty common mixer for stiffish drinks and is usually a bright red color. I’d always thought it a product of some lab, maybe cough syrup gone bad, but I found out it was originally just a pomegrante syrup.
So tonight I made some. Bring two cups of pomegrante juice (I used Pom) to a boil and reduce by half. Lower the heat and stir in one cup of sugar. Simmer for a couple of minutes to dissolve then cool. Delicious!
Should store in the fridge for a couple weeks.
