Drain all water form both of bowls.
Put soaked rice in mixer jar and grind it. We need the grainy consistency. So grind it until its consistency becomes grainy. You can add water little bit if required. Smooth consistency is also fine.
Put urad dal, poha and meethi seeds in mixer jar and grind it. Maintain the grainy consistency of batter.
If mixer gets heats up, then wait for some time. Start grinding again after mixer cools down. You may need to grind all of these in more than 1 batch according to your jar size.
Now put all these batter in one big bowl. Remember that batter should not be too thick or thin.
Now add 1 teaspoon salt in it and mix it well with hand or spoon.
Keep lid on you bowl and leave it for 10-12 hours for ferment. Fermentation time depend on the weather conditions.
After fermentation batter is ready for making dosa.
