But how do you know if your corn syrup has gone bad? Well, there are a few signs to look out for. If the syrup has mold or yeast growing on it, it's time to toss it. And if it has an off smell or sour taste, it's also gone bad.
Don't worry, though - it's easy to avoid spoilage. Just check the syrup regularly, and give it a good stir before using it. And if you're unsure whether it's still good, it's always better to err on the side of caution and toss it.
