Cooks are always constrained and inspired by the area around them. And in that London is unique in that it offers more produce, more variety more inspiration than anywhere. As a city it prides itself on being a trading capital. And with online it is also possible to spread the net even further and source provisions from across the country, all now neatly packed and delivered to your door.  The result is we have our own style of cooking championed in restaurants by the likes of Fergus Henderson, Roley Leigh and Margot Henderson. The home cook though is even more spoiled for choice (without having a menu to worry about). A generation has chosen to kick back against the uniformity of supermarkets and chosen to bring the craft and the artisan skills back that make the difference. Especially bakers. It is also a magnet for international specialists like chocolateirs and gelateria. Others like the Italians have brought their own skills, and more so even the Asians all of which creates a hugely diverse and intriguing larder. If cooking is always about ingredients, then here you can have the best. The recipe is yours.
