This 2016 newcomer to the centuries-old town of Aix-en-Provence lures passersby with samples. Inside, the shop stocks more than 15 varieties of nougat for your test-tasting pleasure, among them, nutella, rum raisin, and salted butter caramel. It’s all sweetened the traditional way, with honey, not sugar, and carved from giant cake-like mounds. Our scientific finding is that nougat works equally well as a sightseeing pick-me-up and a souvenir for folks back home.
