In response, Time Out London issued a short apology for its video, followed by a call for readers to help it with its cultural understandings.

"We've been politely informed that bursting these lovely little parcels of culinary joy before they reach your lips really isn't the done thing at all. So, first off, apologies to anybody who was peeved by our post. Secondly, we'd like to invite the knowledgeable food-lovers of China and Asia to tell us what traditional delicacies we Londoners should try — and how to eat them properly," the editors wrote in an article titled Give us a culinary hand, will you?

Time Out Shanghai on March 31 posted another video on Facebook titled Xiao Long Bao 101, in which the widely accepted way to eat the dish is explained. The video was reposted by Time Out London, with the caption "A public service announcement from our friends at Time Out Shanghai."
