www.coeliac.co.uk Coeliac uk offer diet suggestions, lists of jars/packet foods that do not contain gluten, and I believe some member suggested restaurants. It has a shop, news letter, gluten free food producers sites.
There is a recipe for crumble, cakes, and scones on the site.This is worth you reading and having a look around the site.
Basically, as you may allready know, your foods such as; fresh meat, fish, fruit and vegetables, rice, potatoes and lentils are gluten free.
When you get in to prepared foods, for example, like sausages/burgers the butcher may have added bulking ingredients made from wheat so you will have gluten, make your own as patties with just meat onions and maybe egg to bind, watch out for the breadcrumbs or adding oats, as for gluten.
Watch out for wheat, rye, barley, oats.
You can buy gluten free cakes, and gluten free bread, the supermarket has a section just ask where ever you shop, but always check labels as it may come under another word for gluten.
Phil Vickery (chef) has had sections about cooking gluten free on tv 'this morning', view their website for past cooking broadcasts. He has 'seriously gluten free cooking' cook book different recipes in there for you, (check amazon £13.99).
You will see it is possible to make your own cakes, scones, bread and flour based products, you substitute the wheat/spelt flour for the likes of gluten free flour.
Any jar sauces you cook with, may have to be substituted with your own home made sauces so you can check what has gone in it, or look up the list on the coeliac site for factory produced alternatives.
I hope this has helped a little, and I promise you will get your head round the new food ways soon, just do a little bit of reading, get your ingredients and head off in to the kitchen......... and enjoy.
