Successful New York food writer Tressa Nolan has a great life—wonderful friends, a gorgeous apartment, and of course fabulous food—but the idea of turning forty alone scares her, so she marries the next man who asks: Dan, her building's super. He's handsome and he adores her, but soon after the wedding Tressa regrets her decision. Everything from Dan's unsophisticated interests to his enormous (and intrusive) Irish-American family sets her teeth on edge. Why couldn't she have the perfect marriage her grandparents had? What Tressa doesn't know—what she only discovers when she reads her Grandma Bernadine's journal-cum- recipe book—is that she's following in Bernadine's footsteps, and like all the best recipes, a perfect marriage calls for a long, slow simmer.
