Escoveitch means: A Jamaican and West Indian culinary term for escabeche - fish or meat that is fried and then marinated in a spiced vinegar sauce with onions and scotch bonnet peppers. Escoveitch fish is a beloved. It is mainly Indian English and may not be understood outside that context. There is no real cause for parental concern; it is descriptive vocabulary rather than risky behaviour. This is a food-related word and harmless in itself.
