So, to continue on my with Chapattis story, (Part 1 over here), I made some dough and put it in the freezer. I took it today morning, thinking to thaw it and use it immediately. Unfortunately, even though I waited for it to thaw for 2 hours, it didn't thaw enough for me to make it.
I then put in the fridge overnight and then used it the next day evening. I waited for some time and then started rolling it out. While the temperature of the dough was still on the cold side, I was able to roll it out but I had to fight with the dough a bit. To make the dough easier to roll, I think I may have to wait for it to completely come to room temperature next time.
The chapattis, after I fried on the tava or frying pan, were ok but a litte on the thick side since I wasn't able to roll it completely thinner.
Lessons learned: Put the dough from the freezer in the refrigerator overnight or at least for 5-8 hours before using it. Wait for it to come to room temperature before rolling it out.
