As far as impulse buys go, super-sized prawns would seem like an unusual choice. I was picking my way through Selfridges Food Hall a few days ago, and couldn’t resist these jumbo crustaceans. Selfridges food hall has become something of a weekly indulgence of mine – the produce is excellent, and I often visit the much neglected meat and fishmonger counters to get base ingredients for many of my recipes, making sure to pick up a bag of Torres Truffle Crisps on my way out. It goes without saying, you must visit with an open mind and an open wallet – the fresh produce is Premium in quality and in cost. There are many delicious and obscure condiments, cured meats, cheeses, and sweets. I tend to do mini-shop at Selfridges weekly, and then pop across the road to the M&S Food Hall for the rest.
