Wash the veggies and chop them roughly.
Peel the skin of the garlic and ginger and crush them once with the mortar and pestle.
In a heavy-bottomed wide vessel, add oil and throw in the garlic and onions.
Saute them in a medium flame for 2 minutes.
Now add all the veggies and mix well.
Now add the water and add the whole black pepper and ginger to this.
Now add the coriander leaves | parsley to this and add salt.
Let this come to a boil.
Cover this and keep the flame low.
After 45 minutes to 1 hour, switch off the flame and when it slightly cooks down and you can handle the stock pot, strain the mixture and keep the water aside.
Discard the veggies as all the goodness of the veggies are transferred to the water.
If you are using them immediately, continue; otherwise, you can completely cool this and freeze the stock and use it when needed.
For 3 – 4 days, you can store it in a clean box and keep it in the refrigerator.
