Also a good idea. But I am sure if you note where each store is, in a few hours or so, their recipes will change.

Comedy of errors. First they had the wrong prices. Then they forgot to change the recipe IDs. Confusing as hell.

Anyway, we definitely have an answer to Robin's question. Recipes change when TinyCo changes them, irrespective of whether you've started one or not (i.e. his "short cookbook theory").
