What few treats to pack in your carry-on when leaving Paris

"“Obviously, butter in France is one of the most exciting things,” says Rose, alluding to the array of cultured options available at good grocers in town (don’t forget an ice pack). “You need a great cheese on this list,” Greenspan says. “An aged Comté or a perfectly ripe, raw milk Mont d’Or that’s so runny you can only serve it with a spoon.”

For the dairy averse, or those who don’t want to risk confiscation at customs, Greenspan recommends sweets. “Mazet is an old candy company — from 1636,” she says. “It’s being brought into the 21st century, and the pralines are good.” Or just go to Hirayama and Koreitem’s Mokonuts for lunch and leave with some extra cookies — in flavors like chocochunk, miso and sesame or black olives and white chocolate."
