This is the revised version of the guidelines I sent through to last week's caterers.
"It's salicylate hypersensitivity, which you may not be familiar with.
no pepper, spices or herbs. Most fruit is out and quite a few vegetables.
Banana and golden delicious apple are okay as are chips, baked potato, cabbage, peas, sprouts, lettuce, leek and celery.
All meat, dairy, plain cheese and fish is fine, although fish is especially good. Not sausages.
Small amounts of chocolate as in cake or pudding are fine. No nuts, except cashew nuts if necessary.
Only drinks are water or decaffeinated coffee. Nothing else.
The general principle I work to is that sauces and pies are dodgy. Plain meats, battered fish etc are okay."
Looking at this I suppose I could add:
"the only herb or spice that is okay is parsley and the only sauce is soy sauce, provided it has no additives."
"For cooking rapeseed oil is the best choice."
