This is very rich, so not something I would make often, but it is an absolutely heavenly impress-the-guests-and-then-some dish. I used the "change size" function to cut the number of servings to 4, but ended up with much more food than that, perhaps even double, especially given how rich it is. On the other hand, if you serve it to guests, they may very well be clamoring for seconds, so maybe that's a good thing.
The taste was superb! The sauce was out of this world, NCmystery shopper said it correctly when she said that the unexpected flavors (ginger, horseradish) really helped make this dish stand out. My reservation about the dish is that it is involved and takes quite a long time to prepare. I cut the recipe by a third and it was enough to serve 4-6.
