Recipe notes:
The amount of salt is personal preference within a given range. Start with 1 1/2 tsp. and increase to taste, if desired. If too little salt is used, the vegetables will not be crisp, it will also not discourage the growth of mold. However, if too much salt is used, it can slow and even prevent fermentation from occurring. Salt within the given range of 1 – 2 1/4 tsp. per cup of non-chlorinated water will keep your brine in a healthy range.
You may reduce the amount of salt further, by using 1 Tbsp. whey, or juice from another ferment, per 1 cup of non-chlorinated water. Whey tends to be a little more predictable. I would not recommend reducing salt below 3/4 tsp. per cup of non-chlorinated water.
