Do I need anything other than Syrup for my Slushies to work?
No, you do not need any other bases, the syrup is the base and flavour just add water. Allow 1-2hrs for full freeze, of course this will depend on your machine and how large the bowl is, also your climate. Best thing to do is fill half your bowl with water, add syrup and then add the rest of the water. If you're doing cocktails add water, syrup, water, alcohol. You should notice the bowl to fog up within 10-15mins.
