Eli5: how do fast food franchises keep their recipes a secret and food tasting the same at different locations?

In: Economics

Answer 1

Well practically everything is prepared in a few distribution centers, which then supply all the restaurants in the region.

There is practically no cooking taking place in the restaurants themselves. They only assemble the precooked pieces to form the different combinations.

And the distribution centers also receive shipments of stuff like spice mixes already done at different locations.

The recipes being secret is just partially the result of using a distributed system where everyone just works on their own small part of it with very few people needing to have an understanding of the whole.
