The Tools of the Trade: Neapolitan Influences
The Italian influence on American cuisine is undeniable, with a significant impact from the Kingdom of Naples. Italian immigrants brought with them the secret to creating delicate, luscious pastries, like cookies and cakes, using rich ingredients and sophisticated techniques.
