Success!

Good news! I found the recipe. It was right where I left it, in the last place that I looked. The dish is called "Mushroom Wine Sauce," printed on a page devoted shallot recipes. It was so obvious that I'm not sure how I missed it in my earlier searches. I may need to turn in my researcher credentials.

Anyway, here's the sauce, bubbling away:

That's shallots, green onions, mushrooms, and garlic sauteed in butter and flour, then simmered in red wine and beef consomme. From there, it was good, rich goodness on my grilled steak. To complete the meal, I added a baked potato, marinated asparagus spears, and a green salad with dried cranberries, blue cheese, and walnuts. Topped off with a glass of red wine and it was true Sunday dinner goodness, with enough left over for a Monday holiday. Doesn't get much better than that.
