Place the long grain white rice in a fine mesh strainer. Rinse the white rice well under cold water until water runs clear.
In a medium saucepan bring 1 ½ cups of water to a boil.
Add the rinsed long grain white rice to the boiling water and stir once with a spoon to break the rice up. Return to a rapid boil then cover the saucepan with a tightfitting lid.
Reduce the heat to low and simmer until water is almost completely evaporated.
Once the water has almost evaporated add the ½ cup of coconut milk to the saucepan, replace the lid and continue to simmer until the rice is tender.
Once the coconut rice is done remove the saucepan from the heat and add 1 cup of black beans to the rice.
Stir the beans into the rice and replace the lid, place the saucepan back onto the hot burner and heat until the beans are warmed.
