Mushroom Tarragon Steak Sauce
 
2 lbs. sliced mushrooms
1/4 cup butter
3 Tbsp Soy Sauce (Kikkoman seems to work best)
2 Tbsp Worcestershire Sauce
1-2 TbspTarragon (crushed)
1/2 tsp. corn starch
1/3 cup water
 
Melt butter in a medium saute pan. Add sliced mushrooms cover
tightly.  Simmer until mushrooms are tender and juice is maximized.
Add Soy Sauce and Worcestershire sauce. Cover and simmer for 2
minutes or so to infuse the flavors. Add Tarragon to mushroom sauce
and mix in well but with tenderness for the mushrooms.  Cover and
simmer for 1 or 2 minutes.  Dissolve corn starch in water and add
