Mangalore Buns are prepared with All purpose flour / Maida. I added equal parts of wheat flour. Though the original recipe had given a specific measurement, I simply increased based on how many we need.
Cumin Seeds are mentioned as optional, I suggest you add as it gives a good taste.
Bananas are mostly very ripe that's used, however, I used a medium ripe one.
One might feel odd in serving Sambar and Coconut chutney, however, I recommend you serve with both. It adds up so much taste!
I read that this is normally made the previous night and left to ferment overnight. Since I didn't calculate my banana drought, I had to make it in the morning. I left it on the counter for 4 hrs, then refrigerate till evening to be prepared for dinner. I took it out an hour before making the pooris.
There is no need to add water at all. And it tends to become even moister after fermentation. So knead it again with a little flour to make it easy to handle.
