may be the consistency is loose or not proper

 no amals it was correct as we do for vada.. 

i know only rice dough when fried as balls burst.. no heard of urad dal.. 

then sorry no idea Sugi

 Whatever was the reason.. I got a new recipe..

the name also looks cool "Sirapunji"

gimme the complete recipe please...

 urad dal soaked for one hour. then grind with a pinch of salt. Deep fry  as small balls and keep aside. Now extract coconut milk, add sugar, elachi to it. 

soak the urad dal balls in cocnout milk for atleast 15min. sirapunji is ready.. 

I experienced the same with uradh vada once and still have the scar on my hand/!...The reason was the dough was tight...also that it was little coarse. Share how your dough was.

After this incident I stopped with uradh vada for quite some time..Later tried it in someone's house and felt this should 've been the reason ,comparing mine and friend's dough.

 yes poornima, i think that is the reason.. mine was also tight, since i wanted to make small balls, i didnt add water. also it was coarse.. that could have been the reason.. finally found the mistake.. but the taste was too good.. 

but a good dish...creativity at its best!..will try in my next feast to my friends and inform you!

put a small hole before frying in oil to prevent bursting.I tried the trick when prepared seedai for gookula ashtami.

am sure u wud ve not drained water properly .. this has happened to me also . these days i drain them in a cotton cloth and then grind it .. if u want softer and good bondas u can boil potato and mash them wid this dough and fry it ...

 i too got new receipe, thank u sugi

Thanks to all for the tips...(spl thanks to priyamahesh...and sangita vijai)

anyways 

i have to careful in future ...coz ..

.i too make urad dal bodu for more kulambhu..(same method..of making bonda...then put it in butter milk kulambhu)

 Sugi,

  for sharing ur experience

Kandippa tighta erundhadhala vedichierukka chance ella. There must some small stone or somthing else this won't burst that easily.

good receipe...but high calorie...otherwise I will also give a try...

 uma one day u can eat..

Hey Sugi..is the same wat we call as pal bonda..?...we make small bondas with urid dhal and salt...but instead of coconut milk..at times we will add normal milk also..

hey what is this sweet??? But to my knowledge if the batter is loose u can keep it in freezer for sometime and than use it

really good receipe i feel like trying it but i cannot due to coconut milk it is not good for my MIL and FIL.
