This wonderful tasting, versatile sauce has been a secret ingredient in many southern recipes for as long as I can remember. It was originally patented in 1857. It is used in potato salad, cole slaw dressing, remoulade sauce, egg salads and various other salad/dressing recipes. We love it spread on bread for turkey sandwiches. While the "real deal" is still available at grocery stores in southern states, I understand it is becoming very difficult to find elsewhere. I suspect it will eventually become one of those extinct products that we will reminisce some day. I found several copycat recipes on the net but this one works best for me.
