[Rick and Morty] How is getting the Szechuan Sauce such a big problem?

I mean Rick said it himself often enough, every possible event exist somewhere in the Multiverse.

 How difficult can it be to find a Universe in which the Szechuan Sauce was never discontinued, or to find a Universe where the Mulan film just came out so they still serve Szechuan Sauce at McDonald?

That's much easier said than done. There is no guarantee that a universe exists in which the exact same recipe of Szechuan sauce is still available. And if that universe does exist, there is no time efficient way in which to find it with his existing technology. It's basically trial and error.

Finding it is going to take a lot of luck. His portal technology seems to be kind of blind. He doesn't type in "universe in which Szechuan is still available" and then jump through. He's using some kind of coordinates. It would be like trying to find a specific item/person on Earth by randomly typing in GPS coordinates. You will eventually find it, but it might take a few lifetimes and most of the time you'll just hit ocean. He has to go universe by universe and search the hard way.

In a truly infinite multiverse Rick could visit 100,000 universes per second for trillions of years and never run across the exact same Szechuan sauce. He has to refine the search method or he'll simply run out of time. Rick probably only has a few decades of life left in him. So he can't just brute force search for the sauce for the rest of eternity. He has to think of a new way to search the multiverse for a very specific item and he doesn't have the solution yet.
