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 couldnt she have the perfect marriage her grandparents had? What Tressa doesnt 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.
