Tiramisu (literally “Pick me up”) seems to have been around for generations, but is in fact a creation from the 1970s! The version that we teach at our cooking school in Tuscany uses custard. At home in Italy, people will often use raw eggs, beating the yolks with the sugar and mascarpone, then folding the whites in very gently.
