When heating the butter, make sure you don't brown it
Heat will curdle sour cream so you must take the pan off the heat and let it cool for 5 minutes before stirring in the sour cream.
You don't have to add cheese, of course, but I find it makes this sauce extra rich and delicious.
If you feel the sauce is too thick when it's done, add more chicken broth to thin it. Sometimes I do, sometimes I don't, depending on what I'm using it for.
This sauce keeps well in the fridge for at least a week.
If you have leftover sauce, you can reheat it on the stovetop on low heat but stir it every few minutes.
You can also microwave it but for 30 second intervals. Stir the sauce after each 30 seconds.
