I don’t know if this is an option for you, but have you tried any fondants that are premade? I use Satin Ice and my customers like it more than my MMF because it is less sugary and the texture is less chewy. But I wouldn’t know how to go about lessening the sweetness of my MMF – the only thing I put in it is marshmallows, sugar, vanilla and water :( I would be afraid to mess with the rations. Sorry if this isn’t helpful!
