That's one tasty, profitable accident for MRB!
I've done similar things throwing together a marinade for some meat. We'll be eating dinner, my wife will say "This chicken is great, you can grill it again anytime!" And I'm sitting there thinking "Damn, I need to remember what I tossed in there!"
Funny story: This beer was made by accident. It was one of @MRB Tim's 1st days here and I was tasked with showing him how to brew our MRB kits. I pretty much just grabbed the first ingredients I saw - a Bewitched, a Golden LME, and some Falconer's Flight Hops - and proceeded to show Tim how to make a basic Mr. Beer kit with hops. We ended up fermenting it and this is what came out. Still one of my favorite MRB recipes ever. One of our most popular, too.
