Having recently invested in an airfryer, I was wondering if it would be suitable for roasting coffee beans?  The model I have is this one and goes up to 200C.  Has anyone attempted this with any success? 
Generally lowfat sauces use tricks to get texture and some semblance of flavour. Starches and thickeners give the illusion of richness, while vast quantities of salt somewhat mask the lack of cheese and butter. Anyone with half a palette can tell at first taste though.   Make it seldom, but make it properly.
