We made our simple syrup 50/50 with granulated sugar and SPLENDA (or you could use Splenda for Baking, which is exactly that) and while it will not be quite as thick as traditional simple syrup, you will achieve the same results as with thicker syrup. Use your favorite sweetener if you prefer a natural alternative.Courtesy of Spa Index Guide to Spas and Contributors | https://www.spaindex.com/mascarpone-sorbet/
