In another pan over medium heat, add ½ cup coconut milk and continuously stir until coconut milk turns light brown, lower the heat and continue to cook until it turns to oil and it curdles. Eventually, it will turn dark brown which we call in the Philippines, latik and using a strainer separate the oil and the latik. Set aside the coconut oil and the latik.
In the same pan over medium heat, add the remaining coconut milk and stir for about 2 minutes or until it thickens, then add the brown sugar, salt and then stir vigorously until the sugar is dissolved. Continue cooking until all the liquid evaporates (but do not overcook).
