Condensed Mushroom Soup recipe

Here is a great recipe to make your own condensed cream of mushroom soup. I just made some and I made the recipe x4 and made 4 "can" size. (a can is 1-1/2 cups) So I now have 4 "cans" of soup in the freezer to use in recipes instead of buying cans! I froze them in bowls and popped them out and stuck them all in a ziploc bag in the freezer.
It cost around $.40 per "can size" to make this if you use real milk. I used powdered milk and mixed it with water simply because I am out of milk and didnt realize it til I had already started. Lol. So it would be even less im sure if you use powdered milk.

1 tbsp. butter
3 tbsp. flour
1/2 cup any broth (I used a beef bouillon cube to make mine)
1/2 cup milk (I used 2%)
mushrooms, chopped and sauteed (how ever much you desire)
salt and pepper to taste

Directions

Melt butter in a saucepan over Med-Low heat.
Stir in flour a little at a time until smooth, then remove from heat.
Add broth and milk a little at a time, stirring to keep mixture smooth. Then, stir in mushrooms.
Return to heat and bring sauce to a gentle boil; stir constantly until sauce thickens.
Add salt and pepper to taste.
