I picked up Portland Syrups Spiced Cranberry Syrup at an art/food store in Santa Cruz last month and thought it would be a good time to try this in some cocktails. The syrup has a good cranberry and spice taste, however the syrup is very thin. Like less than a 1:1 sugar to water ratio, it seems.
I tried this in a number of cocktails, basically simple sour riffs with Bourbon, Gin, and Scotch. In no cases could I really taste the cranberry syrup, even when I used more of the syrup than I normally would use in these cocktails. The cranberry taste was totally lost.
I had the same experience when making a Spiced Cranberry Manhattan, a recipe from the Portland Syrup website. It looked pretty but tasted like … a Manhattan. Not a Manhattan with cranberry.
