Condensed Cream Of Mushroom Soup Substitute - cooking recipe

Ingredients

2 tablespoons butter
6 button mushrooms, cleaned and thinly sliced (this seems to me to be about what it looks like from the can, you can always add more or less as you)
3 tablespoons flour
1/2 cup broth (I use chicken but the recipe I based this on the first time suggested beef, it works well with real ) or 1/2 cup bouillon (I use chicken but the recipe I based this on the first time suggested beef, it works well with real )
1/2 cup milk (I have never done this with skim, it works well with 1.5% and whole milk)
salt and pepper

Preparation

Melt butter in a saucepan over medium-low heat.
Saute mushrooms until cooked through.
Stir in flour a little at a time until a paste is formed and remove from heat.
Add broth and milk a little at a time, stirring to keep mixture smooth.
Return to the heat and bring sauce to a gentle boil, stirring constantly until sauce thickens.
Add salt and pepper to taste. I find it usually doesn't need salt and only a couple of dashes of pepper.
