I was surprised to see that your kimchi recipe contains seaweed so I checked online. I love kimchi but never made them at home. This is really interesting! Most of the recipes I found didn't contain the spongy seaweed.
Please send me the link so I can check it out. You got me curious!
Spongy seaweed by: Mica
The seaweed added in kimchi is sponge seaweed. You can probably get this at Korean food stores. Another name for this is codium.
