Joining Meghan, her mother Doria, and a host of event-goers, Harry was the flawless +1, greeting guests, stealing snacks and looking on proudly as Meghan gave her speech.
The Together cookbook will raise money for a kitchen feeding survivors of the Grenfell Tower fire tragedy in west London.
The "Together: Our Community Cookbook", a collection of 50 recipes from the diverse users of the communal kitchen at the Al Manaar Muslim Cultural Heritage Centre, will be used to allow the project to expand and open for up to seven days a week.
Seconds later, another tender moment came when Harry momentarily rested his chin on his wife's shoulder, as she chatted with the women.
For the kickoff of the culinary guide, for which Meghan wrote the heartfelt foreword, she stepped out in a characteristically stylish ensemble including a skirt by friend and favorite Misha Nonoo, and a turtleneck bodysuit by Tuxe.More news: Amazon unveils Alexa-controlled microwave, wall clock and new Echo devices
The launch of the charity cookbook marked Meghan's first major solo project since becoming a royal.
Meghan gave a 3-minute speech without notes thanking the women of the Hubb.
Ms Markle praised the group, saying the diversity of the women was "pretty outstanding" with 12 countries represented. "I could not be more excited about it and proud of you".
"I said in the foreword, this is more than a cookbook and what I mean by that is that the power of food is more than just the meal itself it's the story behind it" the Duchess said. "To be able to celebrate what connects us rather than what divides us, I believe, is the ethos of Together".
Meghan's shoes were by Sarah Flint - a brand she has worn more than 25 times!
Needless to say, the event seemed to go seamlessly and Markle demonstrated what a ideal fit she is for her new role as royal.
