I am not sure if this is meant to be subtle pro-marijuana propaganda or just a brand name thought up by someone who has no idea what “maryjane” may also mean. These buns are enriched – presumably to make them appeal to parents who are buying them for their children. According to the marketing, these buns are “old fashioned enriched” – I may be wrong, but I am pretty sure that in the old days, food was natural and not pumped full of gimmicky chemicals to make parents buy them.
-- want some for mah munchies !
