Using the blood orange extra virgin olive oil, grease one large 2 quart heat resistant casserole/bowl/mold or up to six smaller 6 oz. ramekins, bowls or molds. Arrange the cut up fruit in the molds. In a small bowl, sprinkle the gelatin over 1/4 cup of balsamic and allow to sit undisturbed. In a two quart sauce pan over medium heat, bring the remaining balsamic to a simmer. Remove from heat and add the bloomed gelatin. Stir constantly until no granules or sign of gelatin can be seen and the mixture is completely clear. Pour the warm mixture into the prepared molds and refrigerate for at least 4 hours or until set.
