Nothing beats the thrill of discovering a chic new neighbourhood eatery... except, perhaps, the delicious feeling of eating restaurant-quality food you've whipped up in the comfort of your own home. Tragically, you will have to do the washing up, but who cares when you also get to snaffle the leftovers as a midnight snack? Not to mention basking in the adulation and barely concealed surprise of your family and friends as they sample your delicious dishes. So bin those tattered old cookery books and say so long Delia Smith, and tata Jamie Oliver. It's time you entered the culinary major league, with these online cookery courses from some of the restaurant world's biggest players.
