Kumbilappam is famous and variety recipe of Kerala. It also know as "Vazhayila appam" and "chakka appam". Kumpilappam is a cone like structure, so the name is came from its structure. It's main ingredient is 'Jack fruit' (in Kerala known as 'Chakka Pazham'), other ingredients of this recipe: 'Rice powder', 'Jaggery' (it will made from sugar cane), 'Vazhanayila' and 'Coconut'. I don't know correct procedure of making Kumbilappam. I include a link of making Kumbilappam of Sree's Recipes blog. If you feel it good, please give your comments.
