What is your not replicable delicacy?

so since being at home for spring break, i'm starting to realize that there's certain things that just don't taste the same when being made by someone else. for example, i rly miss porridge and spring rolls made by my grandma, and no matter how perfectly i remake the recipe - it ends up tasting not the same.

do you guys relate at all? and if so, what is your not replicable delicacy, and who important in your life has a hand in creating this delicious treat?
