started me thinking. there are gelatin-like thickening agents made from japanese seaweeds.
https://en.wikipedia.org/wiki/Agar hmm looks like its from a similar species to irish moss. red seaweeds.
my brain is fried from the heat, but there are even other similar things
anyway, i wish seaweed was more commonly eaten in north america. it is incredibly good for you and imho doesnt have any particular strong taste.
