Lisa Ludwinski opened Sister Pie just about a year ago in a former beauty salon in Detroit’s West Village neighborhood. Her grandmothers grew up in Detroit proper (Ludwinski grew up in the suburbs), and after working for a year at Momofuku Milk Bar in New York City, she knew it was time to go home. She started selling her pies at markets, and the community rallied behind her sweet-salty chess version—and her palpable energy, which she channeled into a 24-hour dance-a-thon fundraiser.
