When your bites are separated by anything greater than ten minutes (in this case, fifteen minutes), then habituation no longer occurs, which means that every bite is as good as the first and a bite of gumbo is never better than a bite of partridge. In other words, if you could eat slowly enough, then variety would not only be unnecessary, it would actually be costly, because a bite of gumbo would always provide less pleasure than yet another bite of partridge.
