The Indian cookbook author Raghavan Iyer experienced his first Thanksgiving, in Minnesota, in the early 1980s. “Coming from a land of spice, I thought, ‘Man, how boring,’" he recalled. He shared this recipe for squash dumplings in a creamy tomato sauce spotted with cashews and raisins, a bright and spicy dish welcome on any table, any time of the year. In a pinch? The sauce and dumplings can be prepared a day ahead and refrigerated separately. (Photo: Andrew Scrivani for NYT)
