Basic Grenadine Recipe
Because I like the tartness of pomegranates I usually go easy on the sugar, or I omit the sugar completely when making a reduction. This allows me to use my syrup not only in cocktails but as a dressing or marinade for savory recipes. It can also be made with honey.

2 cups pomegranate juice (I can't advise you on a good method because I always make a mess no matter how hard I try)
1 cup sugar (or less if you prefer it not so sweet)

Bring juice to a simmer over medium heat and cook until reduced by half. Reduce heat and add sugar, stirring constantly until it dissolves, about 2 or 3 minutes. Allow liquid to cool completely and then refrigerate. It should last about 1 week.

....is there time for homemade grenadine too??
