Is an unopened jar of pesto still good?

Whether an unopened jar of pesto is still good depends on the storage conditions and the expiration date. Here are some factors to consider:

1. Storage Conditions:

- Pesto is typically made from fresh ingredients, including basil, olive oil, garlic, and nuts. It is important to store unopened pesto in a cool and dark place, such as a refrigerator.

- When stored properly, unopened pesto can last for several months.

2. Expiration Date:

- Check the expiration date listed on the jar of pesto. This date is usually printed on the lid or the side of the jar.

- If the expiration date has passed, it is generally not recommended to consume the pesto.

3. Appearance and Smell:

- Before using unopened pesto, inspect the jar for any signs of spoilage. Check for any bulging or leaking in the jar.

- Open the jar and check the color and texture of the pesto. If it looks discolored or appears separated, it may not be safe to consume.

- Take a whiff of the pesto. Fresh pesto should have a pleasant aroma. Any off-smells, such as a sour or rancid odor, could indicate spoilage.

4. Taste Test:

- If you are still unsure whether the pesto is good, you can perform a taste test. Take a small amount and taste it. If it tastes bitter or has an off-flavor, it is best to discard it.

5. When in Doubt, Throw it Out:

- If you have any doubts about the quality or safety of the unopened pesto, it is better to discard it rather than risk consuming spoiled food.

Remember that pesto contains perishable ingredients, so it's important to practice proper storage and follow the expiration dates to ensure its quality and safety.
