In a medium saucepan, combine all of the ingredients except the salt and bring to a simmer. Cook over moderate heat, stirring occasionally, until the cranberries burst and the sauce is jammy, about 15 minutes. Scrape the cranberry sauce into a heatproof bowl and let cool completely. Season with salt and refrigerate until chilled. Serve the sauce cold or at room temperature; stir in a few tablespoons of water if the sauce is too thick.
