Mix ingredients and refrigerate. Let the flavors meld for a few hours or overnight before tasting. NOTE: It'll be a whole lot different color (real pale yellowish), compared to the neon color of the sauce you get at Burgerville. If you're going to use it for a burger, spread it liberally on your toasted bottom bun, then place a large dollop of ketchup on top of the meat or cheese on top of the burger. The combination of ketchup on top and spread on the bottom is the way it was done. NOTE 2: Red (hamburger) relish found at Fred Meyer (usually). Hard to find otherwise.
