I know what you mean about artificial sweetener, its not too good really is it. And a lot of S W recipes have it in them! To be honest I think the first time I made it, I left the sweetener out, but cant be 100% sure but didnt replace it with any other type of sweetener honey or sugar! You could experiment a bit, and of course if you like it without then its less syns than going down the sugar or honey route
