We take a trip around the world with BBC World Service presenters and listeners, finding out which are their favourite foods when a celebration is in order. A porridge which is hidden around the house to ward off spirits, sweet and delicious pilau shared with neighbours and an ornate box filled with as many as 50 types of food in Japan – we hear about what’s on the menu at this time of year. Ruth Alexander has help from her enthusiastic three-year-old son to make a traditional Christmas cake for the first time and BBC World Service business presenter Devina Gupta gets stuck washing up after a delicious Diwali feast with her family in Delhi.
