Fermented Rice Pazhaya Soru Recipe FAQs
How do I know if the rice is perfect for fermenting?
The best rice for Fermented Rice Pazhaya Soru is day-old cooked rice that’s cooled and slightly dried out. It should be free from moisture clumps and not have dark spots. Freshly cooked rice is too moist and will not ferment properly, resulting in a soggy texture.

What should I do if my Pazhaya Soru turns too sour or fermented too long?
If it becomes too sour or develops an off smell, it’s best to discard it to avoid any stomach discomfort. To prevent this, monitor fermentation times carefully—typically 8 to 12 hours at room temperature—and keep the container loosely covered in a clean bowl to allow airflow without contaminants.
