An addition to my previous comments: it's rare to find a recipe that is so good in its original form, yet so amenable to embellishment. Thank you so much, again!
Did this as a side for Christmas dinner, with bacon, scallions, and sherry as an addition. The mushrooms must have had a lot of moisture, because the thing collapsed to the point of ugly, but, still, there was none left!
I made this for the first time for Thanksgiving and it came out great. I have since made it with some variations/additions. Bacon is a natural. Spinach was good as was bay scallops.
Thanks!
In general, I go with "When in doubt, throw it out." In this instance, though, we are talking about salted beef, and salting is done as a preservative. If it were me--and this is just for me--I'd reheat it and use it. JMHO
