I DON T think your readers should take much notice of Caitlin Moran s opinion of Walter Purkis s fish shop in Crouch End not being a real one (Who s Who, H&H Broadway March 13). It is one of the two best in north London, the other being in Muswell Hill.

No supermarkets compare for quality, selection and general expertise. Most of the smoked fish is cured on the premises in smokeholes built by my grandfather in 1883.

Supermarket fish is smoked in kilns which were designed to cure fish to an acceptable standard with the least skill required, rather than to the highest standard.

I would not question Caitlin Moran's professional expertise and I hope she will not question mine. After more than 50 years in the fish industry, and at one time selling more than 12 tons of fish a day through my retail outlets, I still do not regard myself as a retired expert but as one who probably knows more about the industry than most.
