Cheezz...going gluten free....
My friend Shauna is the author of the blog "Gluten-Free Girl" and while she doesn't go into depth about how the wheat flour alternatives work together (some she's still learning about), there's a nice collection of recipes on her blog (link below). She also has a collection of links that may be helpful.
Knowing Shauna has been a real eye opener to gluten intollerance. Gluten hides in places you'd never expect (nuts...to keep them from sticking together when shipping), etc.
I'm very serious about this...my best advice is when dining in public, tell the people immediately that they are gluten-intollerant. The chef knows his recipes and his ingredients and can help navigate the menu or make necessary substitutions. You can't have them on your side if they don't know they need to help. Even if you know how to cook and KNOW how things should be prepared, it's best to say it up front.
I did an interview with a girl this summer who was selling ice cream at the farmers markets. If you've known me for 2 minutes you know, I'm an ice cream freak and I KNOW how to make ice cream. Well, she starts telling me about her custard base and mentions she puts FLOUR in it. "Stop the press! Flour? Really???? Why? And most importantly, do you have a sign telling people that?" She didn't know why the base had flour, she was just following a recipe she found (there's one in Fannie Farmer's book, for example) and she didn't disclose it because she didn't see the need. It was an innocent oversight that probably made a lot of people sick. (Since then, she quit using flour at all.)
I know how to make ice cream and have made it hundreds of times. Until I met her, I never saw a recipe with flour in it. Since then I've done a ton of research about ice creams and the properties involved in using starches (flour, potato four, cornstarch, etc.)
But the bottom line is, I would have NEVER suspected flour in a simple thing like ice cream. And given the chef factor and creative license...it's just that easy to get contaminated. And trust me, a simple contamination like that would flatten my friend Shauna for 3 days.
My standard m.o., if you have an allergy, before eating anything in public, ask about it. I know it's a pain but I really love Shauna's attitude. She's helping educate people about the importance and risks.
