Liquid nitrogen cocktail Liquid nitrogen cocktail A liquid nitrogen cocktail is any mixed drink whose preparation involves the use of liquid nitrogen. Popularized as a novelty because of the smoky, bubbling "cauldron effect" it produces, liquid nitrogen is controversial as a cocktail ingredient because it boils at and its consumption is thus potentially lethal. However, it is not a regulated substance in most countries and there is little control of its use. The culinary use of liquid nitrogen is mentioned in an 1890 recipe book titled "Fancy Ices" authored by Mrs. Agnes Marshall, but has been employed in more recent times by restaurants
