The first day of Aadi month (Aadi pirappu) is celebrated as Aadi Pandigai. This festival is important for the newly-weds. The son-in-law is invited on this day for food and gifted with Thengai paal in a 'Silver tumbler' alongwith clothes and sweets. In addition to general pandigai menu, we prepare thengai paal for this pandigai instead of regular payasam. Click here for 'Thengai Paal' recipe.
Coconut rice, Lemon rice or Puliyodharai, Sarkarai pongal and curd rice alongwith poricha appalam. Admire the tactics of our elders. Nothing will be spilt while travelling to the banks of the river and cooking is also simplified .
Some families have the tradition of lighting the Maavilakku on Aadi Fridays.
Some other prasadams (offerings) on aadi vellikkizhamai and Varalakshmi vratham are Ammini Kozhukattai, Manjal Pongal, Arisi Payasam, Pacharisi idli, appam, and vadai. As I am an iyengar, we don't observe this festival. I will update this post after getting details regarding of the vratham and decorated kalasam from my neighbour. However, these are procedures done as per family traditions and many books are available in stores as to how to perform the pooja. Lakshmi poojas are done on Aadi Fridays chanting Lakshmi Ashtotharam and slokas and doing archana with flowers or kumkum to Goddess Lakshmi. The Lakshmi Ashtotharam and slokas can be googled and books are available as well.
