I have an allergy to some cheeses but not too serious so I can experiment. It seems to be mainly cheddars but not many. I get a prickly heat sensation and my asthma plays up a bit. Same with some chillies but again not many. Oddest reaction I have though is with smoked mackerel. Floors me with stomach cramps for about an hour. Unsmoked mackerel is fine as are all other types of smoked fish I have tried. Must be a Gnome thing:-)
