Really enjoyed this; the sauce was a bit greasy at the end, so we scooped some of the grease out with a spoon and then left it for about 15 min. uncovered and it seemed to help reduce the grease quite a bit. May reduce or eliminate the butter next time to see if it helps with that. The only thing I did differently from the recipe was to add 1 tsp. beef bouillon granules because some people used beef brother vs. water - I didn't have any, but this worked out well. Will definitely make again - was wonderful!
