Appe or Appo or Appa is a rice dumpling made using the "Appe Mould Pan" or Appe are small round savoury steamed cakes usually made with a batter. An Appe mould or tava is easily available in all good brands in India. In most branded cookware it is known as "Die-Cast Paniyarakkal". The Indian one has just 6-7 holes, but the pans available outside India have more holes and it is called Aebleskiver pan. This Aebleskiver pan is used for making traditional pancakes in most countries.
This pan is a must for making these delightful little balls of goodness.
I have used simple idli like batter, but there are different varieties of Appe like those which are sweet and also some which are savoury.
This is the simplest and easiest of them all.
