2 c. orange juice
1 tbsp. pineapple juice
1/4 c. basil oil (basil oil can be made by infusing 1 c. olive oil with a whole bunch of fresh basil)

Reduce the orange juice and pineapple juice in a non-reactive saucepan over a high heat to a syrup no more than 1/4 cup. Add equal amount of basil oil. This will make a "broken" sauce, one that separates on the plate.
