Why do we find random things that we love but can't replicate?

I am a wonderful replicator. I can often find a way to reproduce recipes that I like to much acclaim. However, we all have a few things that just really make us happy yet we can not ever seem to reproduce these things, right? Here are mine:

• Stones River Country Club balsamic vinaigrette: Oh my. The best balsamic every. Little bit tangy, little bit sweet. Can't find anything close outside of the CC.
  
• Fresh Express Ginger Sesame dressing that comes in their Asian salad kit: the perfect combo of flavors without being bitter. Yum to the max...except the kit cost $4.50 when it isn't on sale.
  
• Fried pickles like they had at Puffing Billy's circa 1998-2001: battered to perfection in a thick, bready coating instead of a thin crumbly layer. I have tried everything possible and can not recreate that breading. The closest thing is panko, but panko is not what they used.
  
• Pizza like Jet's or Pizza Perfect: a thick Sicilian crust that comes out crisp and delicious.
• Honey mustard from Zaxby's: what is up with this one? Absolutely no honey mustard on the market has the perfect sweetness AND zing of Zaxby's!
• Waffle house eggs: how do they make them so perfect when I can see them cooking them and they aren't adding anything out of the ordinary??
• Demos' chicken and rice soup: I have tried recipes that I've found online, including the lemon juice that I know they add, but mine came out with a broth that is entirely too thick.
  

Anyway, can you tell I'm hungry but avoiding a late night meal?? All of the things on the list make my taste buds very happy and but wallet very empty. Maybe I need to try again!
