Hi. Here is the recipe that I use and Ive never failed at it.
Melt in frying pan:
2 Tablespoons butter or margarine
Add to melted butter and stir
2 Tablespoons flour
Now pour in 1 cup of chicken broth. And cook for about 1 minute.
Hope you try it. You can use any flavor broth you want, I just always use Chicken Broth. Happy New Years.
