To cook upma, first roast suji in a pan until it becomes fragrant and looks dry. Do not stir too long that suji turns brown. Then, heat a pan with ghee/oil and sauté chopped onions, green chilli, cashew nuts, urad dal (optional). Then add water to the mixture and salt as required. Stir for a while and then slowly add roasted suji. Remember to continuously stir the mixture while you add the suji to the pan. Cover and allow upma to steam for a while. Then it will be ready to serve.
