1. Create a brine by dissolving the salt into the water.
2. Take the cauliflower and fill up the mason jar with it. Make sure the pieces are not too far away from each other. Pay attention to the rim of the jar and keep the cauliflower 2” below it.
3. This step is only for those who want to spice the cauliflower with something else. Most common spices are mustard, celery seed, fennel seed, peppercorn, while putting in garlic cloves is also an option.
4. If you want the pure taste of sour cauliflower then leave these out of the picture.
5. Pour the brine into the jar filled with cauliflower. Be sure that the whole cauliflower is covered in brine but also leave some space on the top of the jar.
6. Install the airlock kit on the jar. Please take a look at the instructions on the kit and make it right.
7. Simply take the jar to a place with room temperature and leave it there for 4 days.

These six steps are the right way to have cauliflower fermented. Once you have completed them, give the fermented cauliflower a try. Is it sour enough? If yes, replace the airlock kit with a regular lid and store the cauliflower in the refrigerator.

In case you are not pleased with the sourness, continue fermenting for another two weeks for the cauliflower to reach your expectations.
