I've never heard of them! I am reminded of this snack when you mentioned FUGU. Since you mentioned it's savory, that exactly tasted like this snack below. By the way, did you know about Foodiees bee hive? The community is also supported within OCD incubation project too.
I reckon any snack/food taste-test will be better suited there. As per our rule in the description, " try and submit your content to the more appropriate communities before OCD unless you feel it doesnt belong in any and is original content that works with our rules." So, hope you subscribe into that community and write more content like this!
Those look like they'd be fun as well! And thanks for letting us know of the Foodies community, we weren't aware of it. We'll definitely post there the next time we write about food! :D
