It's a traditional appam that's not known to many... I learnt it from my mom and granny..Granny says they used to make it as a special break fast dish or as a main course on important events like the previous day of weddings , wedding mornings, naming ceremonies etc . Involves a few steps..But it's fun to make it .Very tasty too..Yeast is only a substitute for Toddy. If toddy is available that's the best.
Goes well with Kerala style 'Thenga varutharacha chicken curry'.
