Esrog
An esrog should be wider toward the bottom, growing narrower toward the top. There should be no black spots on the upper half that are visible to the eye when the esorog is held at a normal distance.
An esrog is pasul if it is round like a ball.
A spot disqualifies an esrog under the following conditions:
- If the spot is black, not brown or white as made by a leaf touching the esrog during its growth.
- If the spot is noticeable when the esrog is held at a distance of 12 inches.
- Only if the spot can be seen without searching for it.
- Only if the spot is on the upper half of the esrog. Only multiple spots will disqualify the esrog on its lower half.
If the pitom broke off of an esrog after growing with a pitom. (Yanaver esrogim generally grow without a pitom and are therefore kosher.) This is only true of the pitom broke off entirely at its base on the fruit and none of it is left sticking out.
