Pottukadalai Vella urundai is made for Karthigai Deepam in my mil's place. Many other Brahmin families don't have the tradition of making this pootukadalai urudai for Festivals as they don't consider it as auspicious. Being the native of North Arcot District in Tamilnadu, in my inlaws house for every function it is a must. Even for weddings, seemandams, ayushomam, Grahapravesahams, one among the Paruppu thengai they make should be Pottukadalai paruppu thengai. But being a native of Tanjore brahmins, initially my mom felt so odd to make this pottukadalai urundai and give it for festivals as Seer. Later she got used to it. Even for Karthigai Deepam too we make small Paruppu thengai, but since my mould which i keep here is bit big, i just made urundais. I just finished making pori urundai and pottukadalai urundai this morning for evening neivedhyam. Wishing all my readers a very Happy Karthigai Deepam. Let the festival brings abundance of joy and wealth in your homes.
