This spicy vegetable pickle is a well-known specialty in north indian homes where it is often eaten as a side vegetable. I actually tasted it the first time at a restaurant in delhi where i ended up eating larger servings of this pickle than anything else. You can eat this pickle as soon as it is made. If you wish to consume this pickle within 2 or 3 days, add only 2 tablespoons of mustard oil, but refrigerate the pickle. If it is to be stored for a longer period, you need to add the specified quantity of oil.
