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
Freeze-dried ice cream Freeze-dried ice cream Freeze-dried ice cream is ice cream that has had most of the water removed from it by a freeze-drying process, sealed in a pouch, and requires no refrigeration. It is also known as astronaut ice cream or space ice cream, typically a slab of ready-to-eat dehydrated ice cream. Compared to regular ice cream, it can be kept at room temperature without melting and is more brittle and rigid but still soft when bitten into. It was developed by Whirlpool Corporation under contract to NASA for the Apollo missions. However, it was never used on any Apollo mission.
