We were led to the back of seaside restaurant to select our lunch from huge tanks. There was a fantastic array of crabs, prawns, crayfish, sea snails and fish of varying sizes and types, and we could have had each item prepared in at least a dozen different ways. It was all too overwhelming, so we did what any sensible diner would in such a situation—we ordered what the table next to us was enjoying. And this dish proved to be the perfect light lunch we were after.
Make sure you use the freshest of fish for this recipe as it will be just seared in the boiling water, leaving it quite rare in the middle.
