"Risogalo is that classic Hellenic dish," says Calombaris. "This is a version inspired by my days at secondary school treating myself to a custard tart. If you're having a party, this will work just as well in a bigger version. If you don't want to make the condensed milk custard you can cook the rice in the condensed milk itself and then you get this really creamy, really beautiful rice." Start this recipe at least several hours ahead so the caramel custard has time to set.
