Panchamirtham is the sacred fruit salad offered as neivedyam to deities at home, and also used for abishegam (bathing deities) in Hindu temples across Tamilnadu. The most renowned Palani panchamirtham is prepared using unique bananas that are exclusively grown near Palani hills. It is offered to Lord Muruga in Palani temple and also to devotees as prasadam. You can check out this video to see how panchamirtham abishegam is performed to the deity in a temple.
Panakam is a traditional ayurvedic lemonade offered as neivedyam to deities at home on the day of Sashti Viratham (fasting) observed by Saivites and also on the day of Rama Navami celebrated by Vaishnavites. Rama navami is celebrated on the birthday of Lord Rama and Kandha Sashti Viratham is usually observed on the Sashti thithi of every month and is also observed for seven consecutive days in the month of Iyppasi after Deepavali.
Aval puttu is a traditional sweet prepared using beaten rice mainly for Chithirai Vishu (Tamil New Year). We usually offer this sweet dish to the deities at home as neivedyam during festivals especially Chithirai Vishu and also serve as prasadam during Navarathri. Beaten rice (rice flakes) is easily digestible, and the gluten in rice is reduced to a large extent when beaten. So we can also serve aval puttu as a light healthy snack on other days.
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 medhu vadai of crispy golden skin. Nevertheless medhu vadai is a commonly prepared evening snack in our family particularly during monsoon.
