Delicious & Easy
Place red beets and yellow beets in separate medium mixing bowls. Divide kohlrabi evenly between the two mixing bowls. Add 1/2 teaspoon of sea salt to each bowl and mix well. Set aside for two hours or overnight at room temperature.
After two hours or the next day, transfer each bowl of salted vegetables, and its juices, into separate sterilized jars*. Divide the jalapeños, celery, pickling spice (if using), and fennel fronds evenly between jars.
In a large bowl combine the water, vinegar, and 3 tablespoons of sea salt, mix well until salt dissolves. Pour into jars until vegetables are fully covered. Secure the jars with their lids and gently shake to release any air bubbles, place on the counter for 3 days and then into the fridge for up to 1 month.
*To sterilize your jars, fill them completely with with boiling water, including lids, and let sit for 1 minute. Carefully empty them out and then air dry
