Hi i was reading a thread a few moments ago and saw how some of you have said that you burn your slimming world chips. HOW? I can't seem to get mine to brown off. Any ideas what I'm doing wrong? I part boil them (well i sort of boil them properly till their all soft) then i put them on a baking tray, spray with fry lite and then cook them on about 7 for 45 minutes and they are still white!
