Quick Answer
Signs of successful fermentation in vegetables include a tangy smell, a slightly effervescent texture, and a visible growth of white, cloudy mold on the surface. The vegetables should be slightly soft and yield to pressure. The fermentation process should take several days to a week.
Determining Fermentation Completion
To determine if your fermentation is complete, check the vegetables after 3-5 days. If they are still too hard or crunchy, continue to ferment for another day or two. A good rule of thumb is to wait until they reach a slightly soft and yielding texture. This can take anywhere from 5-14 days, depending on the vegetable, temperature, and level of salt used.
Monitoring Fermentation
Regularly check on your fermentation by tasting the vegetables and observing their texture and appearance. If you notice any off-odors, mold, or sliminess, it’s best to discard the batch. A tangy, slightly sour smell and a white, cloudy mold on the surface are normal signs of fermentation. Use a weight or stone to keep the vegetables submerged under the brine, and be sure to press down any vegetables that rise above the liquid.
Storage and Maintenance
Once the fermentation is complete, store the vegetables in the refrigerator to slow down the fermentation process. Transfer them to a clean glass jar or container with a tight-fitting lid, and make sure to push down any vegetables that rise above the liquid. Be sure to leave about 1 inch of headspace to allow for expansion.
