1. Heat oil in medium saucepan over medium-high heat. Add spice blend; when the seeds start to crackle and toast, add cranberries.
2. Stir in brown sugar, vinegar, ginger, and chili powder.
3. Bring to a boil, then reduce to a simmer and cook until cranberries have softened and the liquid is reduced by half, about 15 minutes.
4. Season the chutney with salt. Transfer to a bowl and refrigerate until cold, about 1 hour. Serve chilled.
