The Duchess of Cambridge's sister will write for the British supermarket chain Waitrose's monthly magazine, sharing "casual dining ideas and recipes" in a column called Pippa's Friday Night Feasts.
Advice published in her 2012 book Celebrate, intended to be a guide to entertaining throughout the year, included using "sharp-bladed scissors" to cut wrapping paper.
A guide to organising a sack race explained how "players start jumping in their sacks towards the finish line", while advice on Christmas catering suggested turkey could be on the menu.
Pippa, who defended her book, insisting it had to "cover the basics", said she "can't wait to get started" with her new role.
