Glow-in-the-Dark Gin and Tonic Jelly Recipe
Arty British food-design/architecture team Bompas & Parr worked with an explosives expert to come up with an edible ingredient to add to Jell-O that would cause it to glow in the dark. Turns out when you make the jiggly dessert using tonic water, it will appear to glow if you shine a black light on it because the quinine in the tonic water is UV reactive. Here’s B&P’s recipe for their eerie, boozy jelly, just in time for Halloween.
- 150 milliliters gin, such as Hendrick’s
- 300 milliliters Indian tonic water
- 50 milliliters Rich Simple Syrup
- Splash of rose water
- 5 gelatin leaves
- UV black light
- Combine gin, tonic water, rich simple syrup, and rose water in a large heatproof measuring cup; set aside.
- Cut gelatin leaves into fine pieces and place in a heatproof bowl. Add enough gin and tonic mixture to cover and set aside until gelatin softens.
- Place softened gelatin mixture over a pan of simmering water and heat until gelatin leaves are fully melted.
- Remove gelatin mixture from heat and stir in the remainder of the gin and tonic mixture. Strain back into the measuring cup. Pour into a jelly mold or bowl and refrigerate until set.
- Unmold jelly by briefly immersing the mold or bowl in a bowl of hot water, then invert over a serving plate. For maximum effect, turn off all the lights and switch on a black light, then serve the glowing jelly to thrilled diners.
