The structure of the zero conditional is:
If + [present simple], … [present simple]..
For example, “If you heat ice, it melts.”
In this case, OP’s sentence (simplified) can be expressed as a Zero Conditional sentence:
If you cut a carrot horizontally, you get round-shaped carrot slices.
The zero conditional is used to state general truths or facts. It implies that cutting the carrot horizontally consistently results in round slices (habitual action).
Some grammar books don’t include the term “zero conditional,” but it’s often used to describe sentences expressing general truths.
If you add “will,” the sentence becomes a First Conditional sentence:
If you cut a carrot horizontally, you will get round-shaped carrot slices.
This version can be used when explaining or giving instructions to someone who may be inexperienced in cutting carrots horizontally, and indicates a specific future result.
