In 1970 when we moved to Houston, Tx., we had some neighbors who were cajun. She made this potato salad, and would bring me a bowl of it whenever she made it. It was always still warm, and had the look of mashed potatoes, but very yellow, yet no mustard taste, and lots of ground black pepper. There were no chunks of onions, or anything else. It wasn't as smooth as you would make your mashed potatoes, but not really chunky. I have tried to duplicate this and have failed. Does anyone have a clue as to what this dish was? Maybe the yellow was from eggs, but there were no pieces of egg whites that you could see.
