Combine pomegranate juice, blueberries, lemon juice, sugar, honey, and cinnamon in a small saucepan.

Bring the mixture to a boil over medium-high heat.

Reduce the heat to low and simmer for about 10 minutes, or until the fruit is softened and the mixture thickens into a syrupy consistency.

Remove the saucepan from the heat and allow the fruit mixture to cool slightly.

Gently stir in the pomegranate seeds.

The fruit mixture can be served warm or at room temperature.

To assemble the crostini, spread softened goat cheese on each toasted baguette slice.

Top the goat cheese with a teaspoon of the prepared fruit mixture.

Drizzle a small amount of honey over the fruit topping.

Serve the crostini warm or at room temperature.
