Mai Tai’s call for rock candy syrup, demerara syrup or a *rich simple syrup. Demerara sugar is harder to find and it's easy to make a rich simple syrup at home. Go with a 2:1 sugar to water ratio - a cup of sugar to half a cup of water. Heat and stir until sugar is dissolved, let cool until ready to use. Store in fridge in an airtight container. It will keep for 2 weeks.
