Big lemon fruit.

This is a big lemon fruit. IS this normal lemon or something else?

 

Perhaps a citron or Ponderosa lemon.

 

Pomelo is another possibility. What is the taste?

 

It is like the lemon taste

 

If the juice is as acid as lemon juice than it is probably something closer to Ponderosa lemon, if the juice is milder than lemon juice than Pomelo is more likely possibility.

 

For sure it is like the lemon taste.
