We were discussing the increasing number of cocktails being served in jam jars. These seem to vary from proper jam jars to a progressively increasing number of re-engineered jam jars which have an added handle.
There's an irony to an erstwhile austerity item being made into something designed and expensive, but probably not fulfilling either purpose of jam container or drinking vessel particularly well.
However, this 'Jamaican-me-crazy' jam packed cocktail was delish. And served in a real jam pot.
