The dishes include coconut chicken curry, aubergine masala, caramelized plum upside-down cake and spiced mint tea.
Kensington Palace released photographs of the Duchess - who also appears on the front cover of the book - chatting, laughing and cooking with fellow volunteers in the kitchen at the Al Manaar Cultural Centre, as well as stopping to play with younger visitors.
A strong gust of wind blew the Duchess's long locks straight up in the air and, without thinking, Harry immediately came to his spouse's rescue, running his hands over her head to pat her down dishevelled 'do. But let's be real here: the optics of the only woman of color in the upper ranks of the family taking her loc'd social worker mother with her to meet with a multi-racial and multi-ethnic collection of women survivors to celebrate their communities and cultures?

The Duchess embraced her friends at the kitchen warmly with three kisses, visibly excited at the success of the book this week and the day of the launch.
The proceeds of sale from the book will support the Hubb Community Kitchen. "I am so privileged to know you", she added.

"I said in the foreword that this is more than a cookbook, and what I mean by that is the power of food is more than just the meal itself. Melding cultural identities under a shared roof. creates a space to feel a sense of normalcy - in its simplest form, the universal need to connect, nurture, and commune through food, through crisis or joy - something we can all relate to".
The palace said the group of women behind the project had chose to gather and prepare fresh food for their families and neighbours, as a way of helping the community to connect, heal and look forward - and to "convene through food".
"To the women of the Hubb Community Kitchen, thank you so much for allowing me to be part of this adventure with you".
