Using Jaggery as Substitute for Sugar
Yes. There would be a difference in texture. Some jaggery tend to be a bit sticky when heated. Groundnut chikkis is a good example. Also, sugar tastes different than jaggery when cooked. Jaggery has an earthy tang to it. In my honest opinion, if you can get good quality jaggery, prefer it over sugar. Simply because its more natural product than sugar.
