One of the best meals was a simple hot turkey sandwich, with gravy.
The gravy seemed fairly traditional or usual for that kind of meal,
but was more "golden" yellow than I've seen in the past. What do you
guys think may have been the ingredient to make that so? I wondered
if a bit of tumeric had been added, but also wonder if there are other
possibilities.

the addition of turmeic wouldn't surprise me since they make so many
pickles and relishes which use it. They'd have it readily on hand.
