I can certainly vouch for Chookies coffee syrup recipe. Not cheap to make but well worth the expense and of course cheaper than buying the cartons of it. Whenever I offer someone an iced coffee these days they always say 'ooh, yes please' and I have converted my SIL to love it so much that he even buys cartons of it when out and about nowadays whereas he never did like iced coffee before. Read my review on the thread to avoid coffee dregs in your syrup.
