Hey staff,
I'm all sorts of for this change.
However, granted it is 36 hours (and in game right now!)...
I had some time to think about it, and there's a worry that some items might require multiple ingredients (some quite rare) -- but if each ingredient is itself food, then the ingredients will expire before you can make the big cake. For instance, flour and ginka fruit, both of which are relatively hard to get, so I can imagine someone getting the flour, then waiting on the ginka, then getting the ginka, but having the flour spoil, so waiting on the flour, then getting the ginka, and [poooooof head just exploded]. (Generally, things that require many ingredients from many different places will be pretty hard to pull off.)
A simple example: I ran a bakery last year and made rat meat pies, which only required two things: rat meat and flour. But it was hard to get both of those together -- either I had a flour shipment come in without the meat or the meat shipment without the flour.
I hope the worry is clear enough.
Perhaps we can bump the expiration up, or have no expiration until certain items can be flagged as more permanent (e.g., tubers and flour shouldn't spoil that quickly) or until preserving containers are implemented -- that is, phase two or whatever?
