海ぶどう umi-budo is an Okinawan delicacy. The name is literally a “sea grapes” and it’s a tasty seaweed. No, it’s the tastiest seaweed I’ve eaten so far, and I’ve tried a few in Japan.
It’s caulerpa lentillifera. It’s also called the “green caviar“. It’s not cheap for a sea produce here, but still affordable. Yes, the taste and mouth feel are caviardesque. It has some resemblance with salicornia or samphire too.
It is loaded with nutrients, particularly minerals like iron and others vitamin. That’s one more Okinawan super-food. But anything they graze there would have magic powers, so they have no merit to still look like kids in their 90’s… You can feel it is loaded with iodine, and very salty too. If you like strong taste seafood you’ll love it, but that’s surely not for everybody. It’s usually eaten raw, with some sour or vinegar sauce to contrast it.
Try it some day !
