This is what I use instead of the cream of mushroom soup. It works terrific. Its kept dry, so easy to use. I use alotta "Dry Mixes" cuz they are so convientent.
INSTANT CREAM OF WHATEVER SOUP MIX
2 cups instant milk
3/4 cup cornstarch
1/4 cup instant chicken bouillon
1 teaspoon onion powder
1/2 teaspoon dried thyme
1/2 teaspoon dried basil
1/4 teaspoon pepper
Combine these and store in an airtight container.
To use for soup, combine 1/3 C mix and 1-1/2 C water. Bring to a boil while stirring often. Add a vegetable for more flavor, such as diced celery (for cream of celery soup), or some sliced mushrooms (for cream of mushroom soup), or some diced broccoli (for cream of broccoli soup).
To use for any recipe calling for a can of cream of mushroom, chicken or celery soup can be replaced with 1/3 C mix and 1-1/4 C water. Boil for a few minutes, stirring often.
