QuoteLiuzhou, nice thread and posts.
Thank you
QuoteOysters (dried) are often added in - that is vegetarian, I think? - but scallops (dried) may also be put in or substituted - and scallops are not vegetarian, if my information is correct.
Oysters are certainly not vegetarian. Whatever gave you that idea? They are no different from scallops in that. No shellfish, mollusc etc is vegetarian.
