Memories work in funny ways. The first thing that jumped to my mind was the Asterix book where the Romans capture the druid (Getafix, in the English versions) and want him to make the magic potion. He insists that he must have fresh strawberries to make it, which are out of season. He doesn't really need them, it turns out, but it delays the whole project as the Romans dispatch someone to points far to the south to try and fetch some and bring them back while they're still fresh.
