The contestants loved cooking. Their everyday ordinariness disappeared when they entered the kitchen. There they thrived and bloomed as they devised or tweaked recipes, gathered and prepared ingredients and, finally, 'plated up' their meal for others to enjoy.
There wasn't a lot of ego there (except for Chris - and I reckon that's one of the reasons he didn't get the crown). The contestants were generous people and their passion for food was all about giving, not taking.
It's all about passion. And giving.
