Make the buri container by swirling the buri leaves on a mold that is about 1 1/2 inches in width. Lock the cylindrical leaf container that you made to prevent the leaf from swirling back.
Wash the rice and then place in a large bowl.
Pour-in water. Let the rice absorb the water.
Pour-in the coconut milk and then add the salt. Gently mix and let stand for 10 minutes.
Scoop the mixture to the buri container and then seal. Set aside.
Arrange the suman in a large cooking pot. Pour-in about a quart of water. Let boil.
Adjust the heat to low-medium and let the suman cook for 60 to 90 minutes.
Remove from the cooking pot. Let the temperature cool down.
Serve with ripe mangoes on the side. Share and enjoy!
