Of course, his name for the sauce was pretty good. After a little research, it seems that the original recipe has never been revealed, but it has origins in India and may contain: vinegar, anchovies, tamarind, molasses, garlic, onions, sugar and salt. I happen to like it and always use a dash when I'm making guacamole for a little extra zip and especially love it on a thick juicy steak. In my house, it will always be called 'What's This Here' sauce, and I am proud to say that I am carrying on the tradition of corny dad (and grandpa) jokes. I can see Abby and Maddy rolling their eyes from here.
