Troubleshooting Your Fermented Red Onions

Onions are floating above the brine Insufficient weight Use a fermentation weight or a smaller jar inside the larger jar to keep the onions submerged.
Unpleasant smell Spoilage, wrong bacteria Discard the batch. Ensure proper sanitation and salt concentration.
Onions are too soft Over-fermentation Reduce the fermentation time. Taste the onions daily to monitor their progress.

Important Safety Considerations

While fermentation is generally safe, it’s important to follow some basic guidelines:

  • Use clean jars and utensils. Sterilization is not necessary, but thorough cleaning is essential.
  • Use non-iodized salt. Iodized salt can inhibit the growth of beneficial bacteria.
  • Keep the onions submerged. Exposure to air can lead to mold growth.
