Gluten is awesome!
But I try to limit my carbs now and I do hate the looks I get when I ask for a gluten free menu just to see the entire offerings of a restaurant(and then I feel doubly dumb when sometimes the menu is just a listing of the already gluten-free plates on the normal menu).
When made well (and fresh), it has the texture of the tenderest chicken or pork you've ever eaten. And, it should not taste like flour, at all. It's mostly the protein from wheat (I use Bob's Red Mill vital wheat gluten, which is 80% protein), and none of the other components that taste starchy or bread-like.
I've been using a variation of this recipe as the basis of my seitan experiments: http://www.theppk.com/2009/11/homemade-seitan/
I make a double batch and still use less broth and water (I use six cups total simmering liquid for a double batch), as the recipe calls for way too much.
For sausage, I add rubbed sage, thyme, cayenne pepper, fresh minced ginger, and white pepper. A touch of brown sugar is also a reasonable addition. Once boiled, I slice it into 1/4" patties and put it into the toaster oven, on a pan oiled with a bit of peanut oil, to broil for 5-10 minutes to make it sizzly and a little crispy. It really is pretty awesome; I serve it with vegan biscuits and gravy (I make the gravy from the remaining broth from the seitan cook).
In short, seitan is one of my absolute favorite foods. I was ambivalent about it, until I had really good fresh seitan at a vegetarian Chinese restaurant. I tried for years to find some at the store that was as good, and was always disappointed. The key seems to be to make it fresh.
