A very interesting jam with the macadamia nuts. I used a large Mexican papaya and found it to be rather bland. The mangoes were green this time of year also - so green they would not ripen. To make a sharper taste distinction, I used 1 1/3 teaspoon of citric acid to add this distinction. Ended up adding 1/3 cup of clear corn syrup to balance out the orange peel and citric acid. My wife loves it.
