  2. Marinated Mushrooms

How can I tell if my marinated mushrooms are still good, and have not gone bad?

Once a jar has been opened, the first sign of spoilage will typically be visible growth of white mold on the surface of the liquid or mushrooms.

If the jar has never been opened, check the pop-up indicator button on the lid. Store unopened jars at room temperature, away from direct sunlight. An indoor cupboard or pantry is an excellent choice. 

Once a jar has been opened, the first sign of spoilage will typically be visible growth of white mold on the surface of the liquid or mushrooms. The product should look in good condition and smell like vinegar, with no foul or off odors. To maximize the shelf life of marinated mushrooms, reseal the jar and place it in the refrigerator, ensuring that the original liquid (brine) covers the top of the remaining mushrooms.  As for similarly pickled products, we expect the product's quality to last up to 45 days or longer when stored properly.
