It’s hard to believe that the humble cauliflower is now deemed to be trendy and so much in vogue that the once-unfancied brassica has usurped kale as the hipster vegetable of choice. But is it really that surprising? For a vegetable it's endlessly versatile and makes a great centrepiece. You can sauté it, blend it to add smoothness in sauces and a creamy texture to soups, but I also love to simply roast it. Roasting isn't usually the first cooking method you think of for cauliflower but the results are quite delicious.
