Combine rice and water in a small saucepan over medium heat. Bring water to a boil. Lower heat and simmer for 15 minutes. Turn off stove.
Pour congee into cracked clay pot and place it on the stove. Turn on the stove to medium low heat. Allow congee to come to a boil.
If there are cracks that go right up to the rim of the clay pot, ladle the hot starchy liquid over the crack to let the liquid seep into the crack. **
Allow the congee to continue boiling for 20 minutes. Turn off stove and let the clay pot and congee cool down.
Transfer half of that cool starchy liquid into a deep casserole dish that can accommodate the cracked clay pot.
Set the clay pot in the middle of the casserole dish so that the starchy liquid will coat the bottom of the clay pot. Cover the entire casserole dish with plastic wrap and allow the clay pot to soak for 3 to 4 hours. ***
Remove the plastic and lift up the clay pot. Pour remaining congee into the casserole dish. Turn the clay pot upside down and wipe the bottom with a piece of paper towel.
Then, pour the congee from the casserole dish back into the clay pot. Place the clay pot back onto the stove.
Turn on the stove to medium low. Bring the congee back to a gentle boil and continue to let the congee cook for 10 minutes.
Turn off stove and allow clay pot and congee to cool completely.
Once clay pot is cooled, discard the congee. Rinse the clay pot and wipe it dry.
Allow the clay pot to air dry completely before storage.
Test The Heal Clay Pot
Pour some water into the clay pot to see if it still leaks. If it still does, repeat the healing process above or discard the pot if you feel it cannot be healed.
Notes
** Cracks may widen slightly as the clay pot heats up on the stove. This is okay as long as liquid seepage through those cracks are minimum. It will stop as the starchy liquid starts to dry up.*** This is to allow the starchy liquid to coat the bottom of the cracked clay pot in case there are any remaining unsealed cracks.
