I sort of agree with pumpkin pie, but I have had some outside of the season and it did not taste as good as it did in the season, which makes me think that my thinking it was good was because of strong nostalgia factor.

My main exhibit for this is the Danish ris a la mande which is during Christmas, it tastes great to me (nostalgia) and Danes if told it's crap will defend it. But foreigners don't taste the goodness, and really if I think about it when eating I start to think: "you know, a tiramisu is better, so is risengrød for that matter, this stuff sort of sucks but I like it."

Ris a la mande also has a specific Christmas tradition associated with it (you have to feel with your mouth for the whole almond in it, and if you find it you get a gift) so doubling down on "it's not taste" explaining the love.
