I don't like X-massy candy/desert stuff, because it's all full of rum and intestines and old man spit.
Well, that just blows my whole image of you listening to the pudding singing in the copper.
It's a good point. More than a few traditional Christmas treats that strike me as kind of gross. My mom used to make fruitcakes that were kind of like brandy-soaked cinder blocks full of dried and canned fruit. Never touched the things.
I'm beginning to lean toward Easter as well. As the holidays go, distinctive treats are probably a bigger part of Easter fun. Putting aside religious observances and just looking at the fun parts, Easter is pretty much all about the treats. Yes, you can paint eggs, and there are brief egg hunts (usually involving candy), but that's about it. Meanwhile, you have chocolate bunnies, chocolate eggs, jelly beans, etc.
Halloween, as previously noted, has a lot of candy, but a lot of it is everyday stuff, or cheap stuff that's really subpar. The act of dressing up and going out to get the candy is much more important. Halloween has the pumpkin carving, the costume parties, trick or treating, scary movies. Not just fun activities, but creative ones as well.
Christmas has some treats. Gotta love the shortbread and gingerbread. Candy canes are not really my thing, but they're distinctly Christmas. And I do have fond memories of the annual box of Turtles my dad brought home. But, there are also presents, cards, pageants, decorations, family gatherings, turkey feasts, parties, parades, stories, movies, TV specials, Santa Claus and a bunch more stuff. Candy is a minor accessory.
Easter, you paint some eggs, find some eggs (often chocolate ones), go to church and get a big basket of chocolate. Candy is a major component of Easter fun. In that light, I have to go with Easter as well.
