Wash and spiralize your zucchini using a Spiralizer or a Julienne Peeler. Place the zuchini pasta in a big bowl, sprinkle some kala namak salt and set aside. This process will help get rid of excess water. It takes about 5min until you start seeing water on the bottom of the bowl. Squeese the pasta gently to get rid of water as much as possible. That way the sauce will be easier absorbed from the zucchini and you wont end up with a watery pasta.
