Would a cream based sauce go well with steaks? I've reached a point where I am very comfortable with a nice red wine/shallot reduction as a pan sauce for my strip roasts/steaks.  I think I remember have a meal once where they served sliced tenderloin with a white sauce.  I imagine it was cream based but I don't often see this combination.

I was wondering if there was hope for throwing together a cream based sauce and if so if anyone had an idea of what base (mother or otherwise) sauce would be a good jumping off point for experimentation?
You may have been served Bearnaise, which is a common red meat sauce. Bearnaise is based on Hollandaise (a mother sauce), a butter based sauce. Hollandaise is somewhat advanced to make because it is important to keep the temperature right and the ratios correct while making it, but the result is worth the effort.
