I read an interesting article on the difference between garlic in Italian Cooking and garlic in Italian-American cooking:
Italy’s Great Garlic Divide
I do recall in some of Shakespeare’s Roman plays that the aristocrats called the plebeians “garlic eaters” or said that they stank of garlic. Clearly that came from the Latin sources.
When we were in Turin in 2006, we had no trouble finding garlic-free dishes.
But here in the states, ‘Italian’ cuisine without garlic is a rarity.
