    The most common cause of a sauce breaking is heating it too high. Keep the heat as low as possible.

    I would agree with others about this sauce regarding the instructions. Both this and the Cowboy Sauce needs to be made in the fashion of a hollandaise sauce. This keeps it from breaking. I started with the Dijon mustard and lemon juice first and mixed well. Then over a simmering pot of hot water (double boiler style), I added the butter (which had been cut up into small pieces) a little at a time while whisking. Near the end of the butter, I started to add in the spices, parsley, and garlic - again in "batches". In the end, I had a nice, thick-ish sauce that paired well with the beef. Cheers everyone! Enjoy cooking!

    I would not use the sauce as a marinade in this one because there is already a spice rub for the meat. You would lose a great deal of the sauce if you used it as a marinade.
