### Clue: Could be Jonathan's original sin (6,5)
### Answer: EATING APPLE 
 ### Explanation: Definition: Could be Jonathan,'s ,original sin
  Cryptic defn(?):  Reference to Jonathan Hasbrouck who "discovered" the apple named after him.  He must have been eating not a few of those apples in his time.  Original sin is the Christian theological doctrine of humanity's state of sin, resulting from the Fall of Man, an event symbolised by Adam and Eve eating of the fruit, symbolised by an apple, of the Tree of Knowledge.
Or if you like it's a double defn: 1st:  An example(could be) of an edible(eating) apple is the Jonathan; and 2nd: Original sin symbolised by apple eating.
