The book will feature 50 recipes written by ladies from the community with a foreword written by the Duchess of Sussex herself. She was accompanied by her husband Prince Harry and her mother Doria Ragland.
The duchess was wearing a striking petrol blue long coat by one of her favourite Canadian brands, Smythe - which sold out within minutes - with a pleated midi skirt by her friend Misha Nonoo, a high neck bodysuit by Tuxe and black suede Sarah Flint heels.
Meghan quickly got stuck in, preparing food that was laid out on trestle tables, dishing out green rice and later flipping chapatis and then watching kofta kebabs, turning them so they browned evenly. She also expressed her heartfelt affection for the project.
Working on this project for the past nine months has been a tremendous labour of love.
Speaking of her work with the community group Meghan said: "I immediately felt connected to this community kitchen; it is a place for women to laugh, grieve, cry and cook together".
She added: There's so many people to thank - I'm extremely grateful because this is my first project and I appreciate your support. "That there are 12 countries represented in this one small room, is pretty outstanding". Everyone has embraced this so fully because it has been a passion project for us all'.
"The power of food is more than just the meal itself - it is the story behind it", And when you get to know the story of the recipe, you get to know the person behind it", she said.
Meghan has been privately visiting the Hubb Community Kitchen, at the Al Manaar Muslim Cultural Heritage Centre in North Kensington, where the women who created the book regularly meet to cook.
It remains to be seen, however, whether the American duchess was forced to spell "endeavour" with the British "ou", or whether she did it out of her own volition. "As they cooked, they began to connect, heal and look forward, and have continued to cook together twice a week".
The proceeds of the cookbook will go towards supporting the kitchen - which is only open two days a week due to a lack funding - and will keep it open seven days a week.
