Step 1: Preheat oven to 425 degrees F and line a baking sheet with parchment paper.

Step 2: In a medium-sized mixing bowl, stir together the cranberries, balsamic vinegar, sugar, and rosemary. Spread the cranberry mixture out evenly on the lined baking sheet. 

Step 3: Place the cranberries in the oven. Roast for 15 - 18 minutes. When finished cooking, the cranberries should be popped open with juices running out. Remove both the cranberries.

Step 4: Place the cranberry salsa in a small serving bowl with a spoon and serve with pita, crackers, or baguette slices for dipping/topping, or:

• Top baguette slices with goat cheese or a slice of brie and a spoonful of cranberries. Garnish with thyme, if desired, and arrange crostinis on a serving platter.
