CREAM OF MUSHROOM SOUP (FOR CANNING)

Why I Love This Recipe
This is a very simple mushroom soup to make and quite tasty and quick. Instructions are for a pressure cooker but a hot water bath works just as well. I don't personally use a hot water bath so I can't advise on the time.
Ingredients You'll Need
1/3 cup butter
1 pound mushrooms, chopped or sliced
3/4 cup flour
2 quarts meat stock (chicken bouillon may be substituted)

When opening to use, add equal amount of milk and soup.
