Baked potatoes, al dente. Mixed with creamy mayo. Chopped hard boiled egg. Bits of crunchy celery and slices of red onion. Dill or pickles to add that slightly sour lingering feeling. A dash of mustard, perhaps the stone kind. Paprika to add that slightly salty, tangy taste. Then a pinch of salt and pepper. Garnish with herbal greenery like cilantro , chives, tarragon.
It’s a mystery what lies underneath all the white things. I remember a chicken salad like this once and the illness that followed.
