If balsamic vinegar congeals in the bottle must it be discarded or can treated to liquefy some way and used?

Here are a few ways to liquefy it and use it:

1. Warm Water Bath: Place the bottle of balsamic vinegar in a bowl filled with warm water. Ensure the water level is not too high, as you don't want water to seep into the bottle. Let the bottle sit in the warm water for a few minutes, occasionally swirling or gently shaking it to help dissolve the congealed particles.

2. Microwave: Remove the balsamic vinegar from the bottle and place it in a microwave-safe container. Heat it on low power for short intervals (10-15 seconds at a time), stirring or shaking the container between each interval, until the vinegar becomes liquid again.

3. Stovetop: Pour the balsamic vinegar into a small saucepan and place it over low heat. Continuously stir the vinegar as it warms to ensure even heating and prevent burning. Do not bring it to a boil, as high temperatures can alter the flavour and quality of balsamic vinegar.

4. Blender or Food Processor: If the congealed balsamic vinegar is fairly solid, you can use a blender or food processor to break it down into a liquid consistency. Add a small amount of warm water or another liquid, such as white wine, to aid the blending process.

Tips:

- Once the balsamic vinegar has been liquefied, store it in a cool, dark place, such as a pantry or cupboard, to prevent further congealing.

- To prevent future congealing, keep the balsamic vinegar bottle tightly sealed and avoid exposing it to extreme temperature fluctuations.

- If the balsamic vinegar has developed an off-smell or flavour, it is best to discard it.
