I'm making some decadent and rather girly Champagne Cupcakes for a party and with the excess fizz I decided to try making a fun little boozy jelly. At Christmas I made some sparkling mulled wine jellies for a dinner party, which turned out to be rather potent and very tasty, so I turned to the trusty Delia Smith recipes once more and found this recipe for Champagne Jelly. I'm adapting it slightly and using Prosecco but it works just as well. Next time I'm going to try adding some sparkling water, a la the mulled wine jelly recipe, to give it a bit more fizz!
