It's the final day of the competition in Hertfordshire and the turn of feisty hairdresser Mel Steel to demonstrate her culinary skills with a mix of French and Caribbean dishes. For once, it's not the food that has the guests rattled, but the request to arrive in fancy dress. Will Charles and Amir quit their sniping and call it a truce? And will Mel's dress code lose her points, or will her eclectic menu be the winning formula that bags her the cash prize?
