What is Mata de Coco made of?

Could you please explain, in simple terms, the composition of Mata de Coco? I've heard it's a traditional Filipino dish, but I'm not sure what the main ingredients are. Is it primarily made from coconut milk or are there other essential components that contribute to its unique flavor and texture? Additionally, are there any variations in the recipe depending on the region or cultural traditions? I'm eager to learn more about this fascinating dish.
