A Japanese food restaurant in Singapore recently attracted criticism online for serving a bizarre-looking dish consisting of a raw octopus egg sack.

Known as tako tamago, the strange dish that landed Singapore restaurant Koji in hot water with social media users isn’t the most appetizing food we’ve ever featured on Oddity Central. It’s basically a large white sack with a very flexible membrane that conceals hundreds of oblong octopus eggs swimming in a viscous fluid. The sack is served raw and melted with a blow torch to release the eggs inside onto the plate. The eggs are usually served with soy sauce and have a taste similar to that of salmon roe.
