This combination of spices, fenugreek, and verjuice used here is what gives these meatballs their unique flavor. I have adapted this recipe from one by Bibi Khanum, who lives in Qom.
For the paste: Place the rice and 4cups/960ml water in a small saucepan. Cover and cook for 10 minutes over medium heat. Add the peas, cover, and cook for another 5 minutes
