No festival is complete with out a feast and here in South India no feast is complete with out vadai-payasam :). Vadai is a deep fried dumpling,where the batter is made of urad or channa dal (for masal vadai).Vadai made with urad dal is also known as medhu vadai (medhu meaning soft in Tamil). As the name says medhu vadai has a very soft inside with crispy edges.It really calls for some experience and lots of patience to make perfect crispy vadai at home.Eating hot vadas just out of kadai is a real experience in itself.Usually in hotels these are served with sambar and chutney but I always like to eat this plain just as snacks.To make proper vadai,first the batter has to be ground to perfection with the correct amount of water.Today's post I am giving my mom's recipe for medhu vadai along with few tips and variations.
