Mix the flour and water, and knead into an elastic dough.
Cover the dough in water, and rest for 1 hour.
Wash the dough (follow tutorial above) until the water is somewhat cloudy, but no longer milky.
Rest the dough for half an hour.
Incorporate seasonings into the dough in a food processor.
Rest the dough until smooth (30 minutes - 1 hour).
While the dough rests, prepare the broth and bring to a boil. Turn down to very low simmer.
Once the dough is smooth, form it into a long "snake," and knot it repeatedly.
Simmer the dough in the broth for 45 minutes.
Turn off heat, and cover. Cool the seitan in the broth for 30 minutes - 1 hour.
If making shreds, shred the seitan while it is warm.
Store shreds or chunks in ziplock bag with as much air as possible removed, or if not shredding/chopping, store the seitan in a tupperware, covered in broth.
Use seitan within 1 week, or freeze (in ziplock bag, without liquid) for several months.
