That's effectively what these are. The new confection from Lotte of Japan called "Wakadama To Kombu Fumi" has a soft chewy outside formulated to resemble the taste of a popular snack called Pickled To Kombu, a type of seaweed. It actually does contain a powdered form of kombu.
Inside the candy is a liquid center with an apricot flavor.
Growing up in a Japanese family, I know seaweed is a pretty popular food source in Japan. But my mom always seemed to go straight for the real thing, chunks of salted kelp pieces. Just suck on 'em, and swallow them when all the flavor is gone. Things have to be so complicated now.
