I have now numerous times heard things such as:
In the final step, the factory adds custom spices for the specific region for which this batch of hotdogs are supposed to be sold.
It is strongly implied, if not explicitly stated, that different "market regions", even within countries/states, have a "general taste".
This strikes me as very odd. Why would that be? After all, we are not talking about radically different kinds of food here, but mass-produced food with "taste customizations" to fit "the palette" of a specific area of people.
I'm not saying that I don't believe that this is done, or that it doesn't have some grounds in reality, but I don't understand it. Especially not these days when every little town needs to have every imaginable race all living there together. How can these different people with only the geographical location in common have a common "taste" in food?
"If the product is sold within these GPS boundaries, add 2.5% sugar and subtract 4.7% salt"? How can this be? How does it happen? Does it really sell more food compared to just coming up with a general "recipe" which is used for every place where the product in question is sold?
