Add the jaggery to the warm water and stir until dissolved. Set aside.
Mix the flour and salt into a bowl and rub in the ghee. Start adding the warm water and jaggery and knead in the bowl to form a soft, smooth dough. The longer you knead the dough the softer the chapatis will be. Divide the dough into eight equal balls. Cover, and set aside to rest for half an hour.
Roll each ball into a thin disc. Heat a tawa or flat griddle over medium heat, cook the chapati for about one minute on each side until it has golden patches. Serve immediately.
notes
When entertaining you could brush the chapati with melted ghee as it comes off the griddle.
