Cruise passengers are big lovers of chocolate. The proof is in the pudding – and the chocolate cake, and the chocolate soufflés, and the chocolate truffles…

And cruise lines are go all-out to satiate this particular craving, creating chocolate masterpieces to rival the best on land. Here are our picks of the top five cruise lines taking chocolate to the next level.

Carnival Cruise Line

Carnival Cruise Line alone buys more than 1.3 million pounds (590 tons) of chocolate each year.

A half million of those pounds go into making the passenger-favourite Warm Chocolate Melting Cake, which accounts for 4 million of the cakes consumed annually in the main dining rooms of the line’s two dozen ships.

And on a single day of the year (Valentine’s Day), Carnival Cruise Line chefs will make some 60,000 chocolate-covered strawberries, along with love-themed desserts.

While no exact statistic is available, it is fair to say that millions of pounds of chocolate are consumed at sea each year on cruise ships. So why do cruising and chocolate go together?

“Chocolate and a lot of things go together,” says French-trained Master Chocolatier Norman Love, who consults on all things chocolate with Princess Cruises. “On a cruise, people are on vacation and enjoying themselves. There’s also a romantic side to cruising and a romantic side to chocolate as well. Cruising and chocolate are made for each other.”

Princess Cruises

The chocolate on Princess’ 18 ships, whose passengers consume more than a million pounds annually, comes from cacao-bean growing countries around the world. As with wine, great fruit produces great product, with sunlight, soil and elevation factors in creating distinct chocolate flavours, Love said.

The chocolate goes into creations including those highlighted in Princess Cruises’ 24-hour “Chocolate Journeys” program (www.chocolatejourneys.com) with Love.

You can sample his 15 extravagant desserts at dinner, bites with afternoon tea, chocolate pastries at breakfast and chocolate cookies while watching Movies Under the Stars.

Or get more adventurous and have anti-oxidant chocolate smeared on your body as part of a hydrating treatment at the Lotus Spa. You can even sip loaded chocolate creations in ship bars.

“Chocolate makes people happy,” Love said. “It’s a wonderful, universal thing that Mother Nature creates.”

Americans are consuming more chocolate than ever before, Love added, whether for health benefits, with an aphrodisiac purpose in mind or just because it’s so good. “It’s chocolate’s time right now. Chocolate is really hot,” Love said.

A recent survey conducted by Wakefield Research for Princess Cruises showed more than half of U.S. adults admit to being a chocolate addict. The survey also showed 70 percent of women would choose chocolate over sex.

Holland America Line

Holland America Line showcases high-end Belgian chocolate in cakes, muffins, custards, sauces and cookies – and more extravagant creations by world-renowned chocolatier Jacques Torres, such as his Chocolate Coconut Napoleon and Baked Chocolate Soup.

A passenger favourite is the Grand Marnier Chocolate Volcano Cake at the Pinnacle Grill. You’ll also find Dutch hot chocolate served on Holland America Line ships on cool days when you’re warming up after seeing, for instance, the stunning sight of a glacier thunderously calving into the sea in Alaska.

P&O Australia

American cruisers aren’t the only ones obsessed with chocolate.

In Australia, passengers on the P&O Cruises Australia ships go for sweet treats even at breakfast, the ships bake a half million chocolate croissants each year.

Cunard Line and P&O

The galleys on British lines P&O Cruises and luxury sister line Cunard stock chocolate in all sorts of forms, including sticks for baking, cocoa powder, chocolate chips, chocolate pastels, cocoa nibs and fudge topping.

And then, of course, there are treats placed on your pillow at night – the two cruise lines will distribute more than 9.5 million wrapped pillow chocolates by British purveyor Whitakers Chocolates this year.

Other brands represented on the eight P&O ships and three Cunard ocean liners include Belgian chocolatier Callebaut and French premium brand Valhrona. To decorate treats, the lines will order up more than 2,700 pounds of chocolate sprinkles (also known as vermicelli) this year.

P&O has introduced a bigger and better all-chocolate buffet, available once each cruise, featuring flowing chocolate fountains, bread and butter pudding, tarts, pyramids, lollipops, éclairs and other creations.

P&O passengers can also try their hand at chocolate making with a new truffle master class, take-home recipes included.

“You should never have a menu without chocolate,” said Kalman Bauer, development chef for P&O, noting chocolate fondant and chocolate soufflés are particularly popular guest choices. “When you have 2,600 people on-board a ship, about 75 percent will go with chocolate at least once a day.”
