Pongal, a harvest festival, is celebrated here to thank the Sun God. Sun is regarded as the creator and sustainer of life on earth, and worshipping the Sun is an age-old practice still followed in India. We could find several hymns praising the Sun god in our scriptures and also several temples enshrining the Sun god (Surya) as the primary deity across India. Suryanaar temple is one of the Sun temples in south India (Kumbakonam, Tamilnadu) where wheat pongal is offered to the supreme deity, Sun God. So we can also prepare wheat pongal instead of rice pongal and offer to Sun God on this Pongal festival.
Medhu vadai or ulundha vadai is a gluten-free savoury doughnut prepared using black lentils (urad dal). Any feast or festival in South India is incomplete without serving soft vadai with crispy golden skin. Nevertheless medhu vadai is a commonly prepared evening snack in our family particularly during monsoon.
Millets are tiny food grains (hence the name), so we can cook them quickly & easily. Though millets are tiny they are nutrients dense food grains. Hence they are increasingly popular among Indians nowadays particularly for the low glycaemic index. There are different millets like kodo millet, barnyard millets, little millets, pearl millets, etc. available in the market. You can refer to the table below for the nutrition data of commonly used food grains & millets. It is useful to compare their nutrients and choose the right one that meets our dietary requirements. Now I have prepared millet payasam using foxtail millets (thinai arisi) suitable for making payasam.
