Step 1: Combine all the ingredients in a heavy nonreactive saucepan over medium-high heat and bring to a boil. Reduce the heat to medium and simmer until the chutney dissolves, stirring often, 5 to 10 minutes.
Step 2: For a chunky sauce, serve as is. For a smooth sauce, puree in a food processor or blender. Use right away or transfer to a jar, cover, and refrigerate.
