A black urad dal pudding mix (Karuppu Ulundhu Kali mix) is a convenient, nutrient-rich blend of roasted and ground black gram (urad dal) with other ingredients like rice, nuts, and spices, designed to make a healthy, fortifying porridge or pudding, often sweetened with palm jaggery, promoting bone strength, digestion, and energy, popular in South Indian diets, especially for women and growing children, and typically preservative-free.
