We had a very pleasant meal at our friends' of shepherd's pie and banana sponge with cream - all salicylate free.
This was the final version of the guidance I sent:
no pepper, spices or herbs (except parsley). 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 and fish is fine, although fish is especially good.
Small amounts of chocolate as in cake or pudding are fine.
Only drinks are water, milk or decaffeinated coffee( or whisky).
The general principle I work to is that sauces and pies are dodgy.
Plain meats, battered fish etc are okay.
We use a lot of rapeseed oil and soy sauce for cooking as both are fine.
