Combine everything except the coconut milk in a pot and boil till red beans or pilot hitam is broken and super soft. Top up water if need be. I used a pressure cooker, so there was no need to top up.
Add the coconut milk and bring to a boil.
Remove from heat and cook to room temperature.
Place mixture into an ice-cream mixture, and churn until mixture resembles soft serve.
Scoop into popsicle containers or a wide pan to freeze.
Needs at least an hour to freeze.
