Add additional water or broth to keep the Seitan covered if the broth level gets low during the cooking process. Combine all ingredients in a 2 to 4-quart pot over medium heat. Bring to a boil and use in above instructions. Cover pan and bring to a simmer on medium heat. Gently place the slices in the simmering broth, then simmer covered for 30 minutes.
Transfer slices to a microwave-safe baking dish and cover with broth.
Remove dish from microwave. Continue to dust with flour as needed. For best results, after mixing let Seitan rest for 5 to 10 minutes on a floured surface. To pressure cook, follow instructions for preparation, except reduce cooking time to 30 minutes after cooker has been brought up to pressure.
