Last night I prepared broiled catfish for our dinner. An hour after that I got so many rashes and bumps. Because I have allergy to seafood. I've been trying to explain to my husband what is Malansa in English and the only word I could think of is Fishy taste. But fish is fish and it has a fishy taste. Is there another definition for Malansa other than fishy? Any Advice? Thanks!!
