Optional: Barbecue Sauce is a great alternative to the tomato jam
Directions:
Combine diced tomatoes, brown sugar, cider vinegar and ground cinnamon in a medium saucepan, and bring to a simmer over medium heat, stirring constantly until sugar melts. Simmer, uncovered, until mixture reduces to 1 cup and is thick and syrupy. Remove from heat and let cool completely. Spoon into a jar; cover and refrigerate until well chilled. To serve, let the jam stand at room temperature an hour before serving. Slice the cheese and arrange on crackers; top each canapé with 1 teaspoon jam.
