Decanter headed out to the Great Italian Chef's and Lavazza coffee masterclass in London earlier this month and were shown how to make this simple but tasty dessert recipe by Christian and Manuel Costardi.

The Costardi Brothers bring the science lab into the kitchen with this inventive meringue with chocolate sauce and vanilla ice cream dessert recipe. If you cannot obtain liquid nitrogen to make the ice cream, simply use a premium vanilla ice cream as a substitute.
