Pink and white, coated with sugar? I thought that was anise seed. In East Indian restaurants here, in Vancouver, its usually in a little dish by the cash register. Like an after dinner mint.
SRS - Its not the big bulbs of the kelp they eat, its the little poppers on the leafy portion of the kelp. They are different sizes depending on the season. We eat alot of seaweed on the islands. They all have different flavours and textures. We even dry it for use in soups. Of course you need to harvest it in CLEAN water. My ex (a fisherman) now gathers seaweed with roe attached. Its a delicacy in Japan. I'm always amazed at how healthy free food is.
