Combine the salt and water and stir until the salt is completely dissolved. You can heat the water in a saucepan to speed this up.
Place the Jicama, Jalapeno, Lime Juice, Cayenne Pepper, and Fennel Seed into the jar. Pour over salted water to completely cover the Jicama. Use a weight to keep the Jicama from rising above the surface of the water.
Cover the lid with a cloth or paper towel and secure with a rubber band. Leave in a warm spot for 1 week, then transfer to the refrigerator.
End Notes and Equipment Needed
Equipment Needed: Mason Jar, Mandolin (optional to slice Jicama), Pickle Weight
The salt water is anti-microbial and prevents the food from souring while it is fermenting. Anything that floats above the salt water is going to be prone to spoilage.
Some mold may form on the Jicama closest to the surface of the jar. That’s O.K. just scoop it off. The Jicama underneath is safe to eat. The Jicama will become sourer as you allow it to ferment. Try it every so often. Once the Jicama has reached a level of sourness that you like place it in the fridge to halt the fermentation process.
The Jicama will stay fresh for about 1 month maybe longer.
