 1 lb mushrooms
 1 T balsamic vinegar
 3 cups water
 1/4 cup brown rice miso
 1 T tamari
 1/2 cup nutritional yeast
 1 t celery seed
 fresh ground black pepper
 1/4 cup cornstarch
 1/4 cup water
 Wash and slice the mushrooms.  Saute mushrooms with the balsamic
 vinegar in a large skillet until fully cooked.  Remove mushrooms from
 skillet and set aside.  Keep the mushroom liquid in the skillet.
 Add 3 cups water, miso, tamari, and nutritional yeast to the skillet.
 Whisk until thoroughly blended and simmer for a few minutes.  Add
 celery seed and black pepper to taste.  Add mushrooms.
 Mix together cornstarch and 1/4 cup water in a cup.  Make sure the
 cornstarch is fully dissolved.  With skillet over medium heat, add the
 cornstarch suspension to the gravy a little at a time.  Stir
 continually.  When gravy reaches desired thickness, cook for a minute
 longer and then serve immediately.
 Note:  If you want to make this ahead, make up the miso-mushroom
 mixture as described but do not add cornstarch.  When you are ready to
 serve it, heat up the miso-mushroom mixture and thicken before serving.
