I would hands down go to Oaxaca, Mexico. When I was 13, we had an exchange student from Oaxaca live with us and his family always sent him food. Ever since, I have been totally perplexed with their rooted knowledge of spices and flavor combinations — from traditional mole to spicy lollipops — it fascinates me. I personally love to cook with chocolate by savory means and I think Oaxacans do it best. I’d love to go there and spend two weeks in a kitchen learning their secrets.
