Also you can use other vathals like manathakkali vathal, maa vathal, mithuku vathal or any vathal for making this kuzhambu.
Add 1/2 tsp chilli powder if your sambar powder is less spicy.
You can even add any other vegetable that you use four puli kuzhambu.
Adding jaggery is optional but we prefer adding it for the slight tangy sweet taste which is so good for this kuzhambu.
