I came up with this basic idea one night, and after a little trial and error, got it nailed down to this. I think it's excellent! It makes an impressive entree for a dinner party or holiday meal.
It is important that you use a good riesling with this sauce. If you are not familiar with riesling, it is a sweet white wine, the best of which come from Germany. Be aware that a "late harvest" riesling may be too sweet for your tastes in this sauce. You may be able to substitute a Gewürztraminer or viognier, but I've never tried it. If using bacon instead of pancetta, do not use a flavored bacon, like maple - just plain old bacon. If you use milk instead of cream, expect your sauce to break. This isn't a low-fat recipe, but it is delicious!
