"The truly historical character – also and perhaps even above all from the point of view of civil, social and ethical history: “national identity”, as we would say today – of Camporesi's reading of Artusi is particularly highlighted and, so to speak, summarised in the famous statement by Camporesi that “”'Science in the Kitchen'“ did more for national unification than ”'I Promessi Sposi . Artusi's tastes, in fact, succeeded in creating a code of national identification where Manzoni's stylistic and phonetic features failed."
