Back when BK came out with their "just like the real thing" burger a friend and I decided to do a real taste test. The BK near us had decent burgers (very important some are just nasty) so we went and ordered one real and one fake, plain made fresh.
We split them and evaluated. Both of us found the fake just weird as far as texture and taste went. They did pour plenty of salt on it but that was not enough.
If you did a fully loaded you might find it acceptable.
Ketchup covers a multitude of sins.
