My sister uses her Sodastream all the time for plain carbonated water. I wanted to surprise her with some ginger syrup that she can mix in, and am thinking about other possibilities.
Most recipes for root beer, etc. assume you want to combine the carbonation process and flavoring through fermentation, but I really just want to make some strongly flavored syrups that are not too sweet. Any ideas? I found a reasonable-looking ginger syrup on Epicurious, but wondered if anyone had any other recipes to share. I realize that a syrup won't last particularly long, but I don't need to make more than one at a time. If it matters, I live in an area with good access to unusual ingredients.
Thanks for any suggestions.
