According to the legend the fruit was created thousands of years ago by fire breathing dragons. During a battle when the dragon would breathe fire the last thing to come out would be the fruit. After the dragon is slain the fruit is collected and presented to the Emperor as a coveted treasure and indication of victory. The soldiers would then butcher the dragon and eat the flesh. It was believed that those who feasted on the flesh would be endowed with the strength and ferocity of the dragon and that they too would be coveted by the Emperor. It is written that the dragons flame originates deep within its body near the base of its tail. The meat from this part of the dragon was the most desirable and most sought after portion. Only the officers of each division would be privy to this cut of meat. The ancient Chinese called this cut the jaina, which translates literally to the sweetest and best tasting. The jaina was treasured by all who were privileged enough to taste it, and it is believed that manís thirst for the jaina is what led to the destruction and eventual extinction of all of the dragons.
The mild and juicy fruit is easily cut in half and eaten with a spoon.
