Fish on Fridays. Flathead Burgers With Marie Rose Sauce.

Flathead Burgers With Home Made Cocktail Sauce

After what seemed to be an awfully long hiatus Australian tiger flathead is in plentiful supply at the fish markets at the moment. Sweet and succulent it is a firm favourite in our house. Like ravenous, circling seagulls my family devour it by the plateful. Gorgeous as it is served with a simple salad, today I decided to try something different. Make it the star attraction of a towering fish burger, replete with lettuce, avocado, tomato and lashings of Marie Rose sauce.

The gorgeously hued, intriguingly named Marie Rose sauce was the stalwart of many a 1970’s and 80’s dinner party. A key ingredient in the ubiquitous  prawn cocktail , a then avant-garde but now passe layered creation of shredded iceberg lettuce, prawns served in a cocktail glass. The sauce, itself, is more familiarly referred to simply as cocktail sauce or even thousand island dressing, easily made from just a few pantry staples; mayonnaise and tomato, Worcester and Tabasco sauces.

Urban legend has it that the sauce was named after the famous Tudor warship, The Mary Rose, which sank in  1545. In the 1970’s a plan was hatched to salvage the wreck and in 1982 the ship became a star attraction at The Portsmouth Museum. Urban legend has it that during the salvage operations a naval chef  on hand to feed the army of workers realised he didn’t have enough sauce to accompany the prawns he was planning to serve for dinner. Improvising with the ingredients he had on hand he devised a tangy dressing and named it Marie Rose sauce after the shipwreck.

Fast forward to 2014, this sauce sweet, tangy sauce is the perfect addition to my delicious fish burger.
