In a small sauté pan, heat oil over medium heat. Add shallot and garlic; cook until fragrant, approximately 3 minutes. Transfer mixture to a medium saucepan. Add plums, raisins, orange juice, pectin, brown sugar, mustard, and coriander; bring mixture to a boil over medium heat. Reduce heat to low, and simmer for 10 minutes. Whisk in wine and vinegar. Transfer mixture to a heatproof bowl. Let cool completely.
Spread 1½ teaspoons blue cheese onto each mini toast. Spoon 1 teaspoon chutney in center of toasts.
Garnish with basil, if desired. Serve immediately.
Notes
Plum chutney can be made up to 3 days in advance, stored in an airtight container, and refrigerated until ready to use.
For best presentation, place a 1-inch square cutter in center of each toast, spoon 1 teaspoon chutney inside cutter, and carefully remove cutter.
