But a second consecutive night of good food leaves businessman Robin Lewis, the only man in the group, feeling the pressure.

Air-hostess Kaaren Kitching is keen to extol the virtues of good honest country cuisine on night two, but her hosting leaves a lot to be desired. Louise Naum is determined that her Czech-inspired food will up the culinary ante, but she also has her work cut out trying to loosen up the rather straightlaced Kaaren.

Episode 15 - All in One: North Norfolk

This week the culinary competition comes from the north Norfolk coast, where two men with very high standards are confronted with two women who take a more casual approach to hygiene.

Completing the line-up are undertaker Helen Wickes and picture framer Dave Parks.

Episode 16 - All in One: Stamford

Come Dine with Me begins in Stamford, Lincolnshire, where the first host is retired aerobics instructor Sue Quinn. Arriving at her door is snobby publican Michael Birt, florist Sophie Cullumbine and foodie Adam Baxter. Sue kicks off the week with a riotous night that sees her immediately clicking with Sophie. Adam thinks he knows why, observing that the pair are the young and old version of effectively the same person - and what's more, he and Michael can't get a word in edgeways. Michael attempts to bring a touch of class to proceedings on his night, with upmarket food and conversation. Sophie, however, has other ideas and is equally as outrageous as on the first night; even Sue despairs of her. When it's Sophie's turn, she realises she needs to reign herself in and be the hostess with the mostess. The boys warm to her over the course of the evening, but after offering up a surprising and unique squirrel dish, the food misfires spectacularly.

On the second evening, Ingrid's flamboyant style is matched by her 'food of the world' menu; alas, it's dust that leaves an unwanted and lasting impression on guests. Super confident Richard Turnbull is out to impress, but come his night, the car salesman has his work cut out with an over-ambitious menu. That said, Richard's food is somewhat overshadowed by Carl's behaviour as he goes a step too far with Charlotte; she takes umbrage at his views on the former Miss Stafford's modelling days. After a week of pushing people's buttons, it's Carl himself who feels he might have scuppered his chances.

On the second night, fashion designer Kay Davidson dons the oven gloves and tries to impress with a fine dining menu and a sophisticated wine tasting game. Once again, Ben upsets his fellow diners, particularly feisty foodie Gemma Sparkes, when he tries to play wine connoisseur. She soon takes him to task over his arrogant attitude.
