It is a Monday evening, just around 7, and Mr. Samuelsson — hotshot chef, food impresario and kinetic force behind Red Rooster Harlem, one of Manhattan’s restaurants of the moment — is displaying his usual verve.
On the red carpet, he snaps a picture of his glamorous wife, the model and philanthropist Maya Haile, with Beyoncé. In the European sculpture gallery, he is chatting with Kanye West and several of the New York Knicks. At the Temple of Dendur, he is dining with André Balazs, the hotel owner, and Chelsea Handler.
The next morning at 10, Mr. Samuelsson, in a fresh shirt and tux trousers, is sitting in a sound studio some 60 blocks downtown, painstakingly recording the audio version of his new memoir, “Yes, Chef.” Six hours later, in a vintage, red velvet tuxedo jacket, he is overseeing an intimate dinner for 350 at Gotham Hall on behalf of Queen Silvia and Princess Madeleine of Sweden.
And the morning after that, Mr. Samuelsson is back uptown to work the lunch rush at Red Rooster, that culinary mosaic of Southern, Swedish and Ethiopian comforts on Lenox Avenue in Harlem.
