Artisanal ice cream sometimes contains unusual ingredients, like foie gras, blue cheese, or horseradish, but Lick Me I'm Delicious' latest ice cream innovation contains jellyfish protein, not for its flavor, but for its luminescent properties.
Food tinkerer and Bristol-based Lick Me I'm Delicious founder Charlie Harry Francis decided to play with the synthesized protein, which he purchased from a scientist in China. Francis describes the proteins (probably aequorin) as "calcium activated proteins that react when they are agitated," meaning that the ice cream emits light when it's licked.
Just don't expect mass-production of glowing ice cream any time soon; it costs Francis roughly £140 per scoop to make. For events, he's making a knockoff; making a gin and tonic sorbet with quinine that glows under blacklight.
