Verity,
Are these the type of goodies you would be interested in?
Asda have now got a good range of GF products, they also do Jaffa Cakes and a Cranberry and Orange Loaf.
I have tried the brownies and they are good, moist and chocolatey, if a little sweet. I made my own using a standard recipe, and I find that the ones made with wheat flour are slightly acidic compared to the gluten/wheat free ones. Similar to the difference between cow's milk and soya milk, I gave up cow's milk in favour of soya milk years ago, and now I can't stand the taste of cows milk.
Coeliac disease is high profile here just now, info was being broadcast in Asda yesterday and I picked up leaflets from a display in the hospital foyer today.
I know that people are bringing you goodies, so if you have tried these and prefer a different brand, just let me know and I can get the ones you prefer.
I'll be there four weeks on Wednesday.
