How do you know if corn syrup has gone bad?

- Color: Fresh corn syrup should have a clear and light amber color. If the corn syrup becomes darker, it may be an indication that it has gone bad.

- Smell: Fresh corn syrup should have a sweet and candy-like smell. If it develops an off smell, such as a sour or pungent odor, it may have spoiled.

- Taste: Fresh corn syrup should have a sweet and slightly caramel-like taste. If the corn syrup tastes bitter or sour, it is likely spoiled.

- Consistency: Fresh corn syrup should be thick and viscous, similar to honey. If it becomes watery or thin, it may be an indication that it has spoiled.

- Mold or cloudiness: If there are any signs of mold or cloudiness in the corn syrup, it is likely spoiled and should not be consumed.

It is always a good idea to check the expiration date of corn syrup before using it and to discard it if it has passed its expiration date.
