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
Ice cream maker Ice cream maker A domestic ice cream maker is a machine used to make small quantities of ice cream for personal consumption. Ice cream makers may prepare the mixture by employing the hand-cranking method or by employing an electric motor. The resulting preparation is often chilled through either pre-cooling the machine or by employing a machine that freezes the mixture. An ice cream maker has to simultaneously freeze the mixture while churning it so as to aerate the mixture and keep the ice crystals small (less than 50 μm). As a result, most ice creams are ready to consume immediately.
