“At the end of the day, it has nothing to do with sex,” said Pinky Cole, 31, who once sold jerk chicken in Harlem and produced a television show with Maury Povich before she started Slutty Vegan. “I know that sex sells, so I thought how I can positively manipulate this. We want you to have an orgasmic experience and the ultimate feeling of euphoria that comes after having a vegan burger.”

Then, she said, “I can guide you to the truth.”

Ms. Cole’s business is hard-wired to connect with several rising constituencies, not the least of which is the food-truck generation, for whom long waits to sample a singular dish are part of the experience.

She is also riding a new surge of the black vegan movement, fed by chefs and stars who have given up eating animal products for environmental, health and humane reasons, and as a way to embrace traditional African diets and push back against Southern foods with links to slavery, like pigs’ feet and chitterlings.

She has also plopped herself in the middle of the fake-meat arms race, in which Beyond Meat and Impossible Foods are battling to be the company whose plant-based protein best mimics hamburger. Traditional meat producers like Tyson and Hormel are preparing to jump into the market, where sales grew 17 percent in 2018, according to the market research firm Nielsen.
