For one of my stories I need to know what they are like to eat, in terms of taste, texture, etc. I've tried searching on this with phrases such as "Pickled starfish" "taste of starfish" etc. but I keep finding entries related to starfish peppers, a restaurant named Starfish, etc.
Unfortunately it really does need to be starfish, no other seafood works for this story, and since I tend to have seafood allergies I can't try it myself - even assuming that I could find them in the UK, which seems a little unlikely.
I'm assuming that they're a bit like squid, e.g. rubbery, but maybe more crunchy, and taste mostly of whatever they are pickled in, but I have no idea what that would be. Can anyone help with a better description?
If anyone wants to know what this is about I've put the explanation below the cut, because it will be a spoiler for the story.
The character is under mental attack from an intelligent starfish (if you read silver age Justice League comics you will know who I mean) and uses the memory to repel the attack.
Later - it looks like this is primarily a Chinese thing, not Japanese, they're sold as street food in parts of China, along the lines of raw sea urchin. It really doesn't sound very nice, but fortunately that doesn't matter for this story,
