This dish is similar to kuzhi paniyaram. The only difference here is you add Channa Dal Moong Dal while preparing the batter. In my MIL’s place during Karthigai Dheepam she makes Uppapam(savory appam) and sweet appam for dinner. She usually deep fries the batter in oil which gives a very crunchy texture to the appam. However I chose to prepare it in Paniyaram/Appe pan.The batter has to be fermented for at least 3-4 hours to get soft appams. So plan accordingly and prepare the batter.
