The logic here doesn’t work for me. Moon cakes are generally eaten only in the week surrounding the Mid-Autumn Festival here in China. It’s traditional, see. Yet they’re incredibly yummy and were they available at other times they’d likely be consumed cheerfully. In Hubei there’s a special dish of “birthday noodles” eaten basically only on your birthday. (And only by you; the rest of your family doesn’t get them.) They’re also incredibly delicious … and literally eaten only once a year.

The fact that something is eaten only seasonally or by special occasion doesn’t mean that it’s not tasty. It means that it’s special, nothing more.
