Serve rendang with steamed rice and sambals.TipsIf using a blender to grind the paste, adding some oil can help these ingredients to blend easily. Do not add water, this will affect the quality and taste of the rendang.If we are feeling lazy, use a slow cooker.

However, use TCC coconut milk instead of cream, as it has a lower fat content and more forgiving when cooking over a long period.
