After the wedding, we were invited by the groom's family for a meal at their place. His mother made some amazingly delicious dishes for all of us! Pesarattu was one of them. I was too small them to bother asking the name, instead happily feasted on them so much, that I remembered the taste 17 years later! Luckily the recipe turned out pretty simple and I could make an awesome batch of the dosas to treat my friends with.
A definite must try!
