Recipe finding failure

We have an enormous turkey I got for free (yay supermarket promotions). So I was thinking about gravy, which we don't usually bother with (for some reason, the gaming group wasn't terribly interested last time we made it). When we were in Lancaster, we had the most amazing turkey gravy. It was a startlingly sunny yellow, full of herbs, and incredibly flavorful. I've been trying to find a recipe, but thus far, total failure. My best guess is that it involves a large quantity of butter and/or egg yolks, but it what proportions I haven't a clue. Sigh. It's probably best - I don't usually like gravy all that much, which is probably good for my heart and my waistline, and if I could make this stuff, I'd gain ten pounds. But oh, it was so good.
