Yes, you can use white or brown rice along with other ingredients. 2 tablespoons of uncooked rice or 1/3 cup of cooked rice, is good for this recipe. Poha (flattened rice) can be substituted for rice. Take 2-3 tablespoons of poha. Rinse and soak the poha for 10 minutes. Drain the poha and grind it along with quinoa.
