SICK OF MACARONS? Need more than a chocolate fix? Stash away some caramels from one of Paris's best pâtissiers on your next trip to the City of Light.

Plenty of chefs inspire loyalty, but Jacques Genin has so perfected his art that someone has been graffiting slogans about him outside his Marais pâtisserie. "Si ce n'est pas Jacques Genin, je n'en veux pas" ("If it's not Jacques Genin, I don't want it"), one message from an impassioned fan declared.

Caramels from Jacques Genin Tina Wong/The Wandering Eater

Earlier this year, Mr. Genin decided to scale down his pastry production to focus on chocolates and caramels. The latter are in danger of provoking more graffiti.

Rich, pliant and buttery, they come in eight flavors: hazelnut, cashew, macadamia, pistachio, chocolate, vanilla, plain and a mango-passionfruit that manages to be both tangy and mellow.

Mr. Genin supplies some of the finest addresses in Paris, including Hôtel de Crillon and Le Meurice. But you can get your hands on his sugary delights directly from his store, where everything is made fresh daily.

Sold individually, or in stainless-steel boxes, the caramels cost €110 per kilogram, or about €1 a piece. With a shelf life of just two weeks, they're a hauntingly evanescent souvenir. Tuck a cellophane pouch in your pocket for a long taxi ride—and a box (or two) in your suitcase. They won't last long.
