The dough for Kerala Parotta needs to rest for at least 2-3 hours, and preferably overnight in the refrigerator, for optimal gluten development and elasticity. This resting period allows the gluten to relax, resulting in a softer, more pliable dough that's easier to roll out thinly.
Resting the dough is a crucial step in making Kerala Parotta. The gluten in the dough, which is formed when flour is mixed with water, needs time to relax. During the resting period, the gluten strands unwind, making the dough more extensible and less likely to snap back when rolled.
Here's a breakdown of why resting is important and how it works:
For best results, after kneading the dough, lightly oil it, place it in a bowl, cover it with plastic wrap or a damp cloth to prevent it from drying out, and let it rest at room temperature for 2-3 hours. For even better results, refrigerate the dough overnight. If refrigerating, allow the dough to come to room temperature for about 30 minutes before rolling.
If you're short on time, a minimum of 1 hour of resting is acceptable, but the longer the rest, the easier the dough will be to work with and the flakier your parotta will be. Avoid skipping the resting step altogether, as this will result in a tough and difficult-to-roll dough.
