As its Father's Day on Sunday, Chef Neil Forbes and Sumayya Usmani are joined in the garden by chilli sauce entrepreneur Gennaro D'Onofrio to cook up some deliciously marinated chicken kebabs and hand-dived scallops on the barbecue. Also, spice girl Ghillie Basan and her friend Bernie prepare lunch over an open fire using an upside down wok and food innovator Simon Preston visits Reekie's Smokehouse in Edinburgh to hear how they are using chopped up whisky barrels to flavour their meats.
