Katie Swain shoots delicious Waitrose spots

Get ready to lick your lips. Here we have Katie Swain's latest work for Waitrose, featuring Martha Collison, the British baker and food columnist who rose to fame after competing as The Great British Bake Off's youngest ever contestant, reaching the quarter-final of the fifth series. Martha whips up a mirror glaze cake, espresso martini macarons and salted caramel chocolate tarts... And they look rather tasty indeed!
