Then they make their own pre-mix in a central laboratory in Turin, seal it in plastic and send it out to all their branches worldwide. All the employees need to do is open up a bag, pour it into a countertop-mounted mixing drum in the display case, and the gelato starts to solidify in minutes.
Some may scoff at the idea of pre-packaged mix. But it solves the quality control problems of operating internationally. And the product speaks for itself. It's good. Flavors are mostly classics: stracciatella, vanilla, espresso, pistachio. But you'll also find unique seasonal flavors, like candied chestnut — definitely worth trying. A smaller selection of sorbets features some flavors you don't see much of here, like apricot and pear. Go for the pear. It's bright, crisp, refreshing.
Be warned, however: Shanghai has an inexplicable proclivity for waiting in long lines for ice cream, and Grom is just the kind of import brand that will attract hordes of selfie-snapping social media-ites. On our visit, the line was just about out the door. I expect it will spill out onto the sidewalk and then some once word really gets out.
Grom, 772 Nanjing Xi Lu, near Shimen Yi Lu, 10am-10pm.
