Paddu is a South Indian dish. It also requires a special type of pan somewhat similar to idlis. But the only difference is Appes/Paddus are not steamed but fried in this pan as shown below.
It has small around an inch deep rounds to fill the appe batter.
Its a non-stick pan, hence requires less oil. Paddu/Appe needs a little of pre planning but its best part is that it doesn't require any fermentation. It can be done right away after grinding the soaked dals.
One of the best n tastiest food I have personally tasted
