Like crayons, chocolate comes in many varieties and tastes better when unwrapped before consuming. Scribble out cocoa cravings with today’s Groupon: for $35, you get a chocolate-making class at CocoaNymph (a $70 value). Groupon customers also get 10 percent off items at CocoaNymph.

The master chocolatiers at CocoaNymph give students a taste of artisan chocolate-making and knowledge of the decadent dessert's history in a flexible schedule of classes. Presented with a block of solid ganache and napkin-ring stencils, up to 12 pupils fashion a collection of dark-chocolate truffles, employing different finishing and decorating techniques to diversify the truffles' flavours, shapes, and ruling planets. Confection mavens indoctrinate aspiring chefs in an intimate café, inspiring a convivial atmosphere for traditional home cooking. In addition to adding to their candy-recipe rolodexes, students indulge in a single-origin chocolate tasting and escort their 16 truffles home to serve at dinner parties or replace missing chess pawns.
