Humans mostly don't eat sweet stuff for calorific or nutritional purposes. Rather I think they enjoy puddings, cakes, chocolate, and so on, for psychological reasons (comfort, pleasure) as well as for cultural reasons. So my question remains.

What should should be served or otherwise laid on at social gatherings that yields equivalent cheer and can be passed down from grandmother to grandaughter?
