For those living in the USA, plain gluten already made into dough is sometimes available in the refrigerated section of Chinese groceries. It is mich cheaper than the seitan sold at health food stores for more than $7/lb.

Also found in Chinese groceries are 2 canned wheat gluten products, whose canning juices can be washed away, although the nuggets themselves have been fried: they are called vegetarian duck and fried gluten. I like the quality and taste of the latter, drained of all oil and liquid. About $1.29 per small can of 6 oz.

At health food stores, you will find enriched wheat gluten, which I think is flour enriched with gluten, not pure wheat gluten, which also exists. Where it can be found, I have not been able to discover, although all seitan makers in the USA import pure wheat gluten from China and hydrate and prepare dough from it on site. So, if people are concerned about various Chinese agricultural products, caution should extend to US seitan, no matter what health food store sells it!!
