Ferment coconut meat to make coconut kefir cheese or ferment the coconut milk to make a coconut kefir drink. The process is simple, though it takes up to 36 hours to complete.
Drill a 1/2-inch hole into each of the coconuts and drain the coconut milk into a measuring cup. Use a Phillips screwdriver and hammer to poke a hole in the coconuts if you don't have a drill.
Use a cleaver to carefully split each of the coconuts in half. Spoon the white coconut meat into a blender or food processor. Remove any brown skin clinging to the coconut meat, if necessary.
Blend the coconut meat into a smooth puree. Add as much of the reserved coconut milk as necessary to make blending easier.
Warm the coconut puree in a medium saucepan over medium heat. Take the pan off of the heat when a thermometer inserted into the puree reads 90 degrees Fahrenheit.
Dissolve kefir starter in the amount of water recommended on the packet. Add the starter and 1 tsp. sea salt to the coconut puree and stir until combined.

Store the fermented coconut in the refrigerator for up to three weeks.
