I have seen several recipes for coffee syrup, but none of them with a simple caramel taste. Is getting the caramel taste as easy as using brown sugar instead of white sugar, or do I need to find some store selling caramel flavour (essence)?
I would actually just make caramel. Place about 1 1/4 cup sugar and 1/4 cup in a heavy bottom pan and dissolve over low-medium heat then crank up the heat and let cook, without stirring, until the mixture turns a golden amber colour and starts smoking. Then use the resulting caramel to sweeten your coffee :-)
