I really, really liked this. I wondered just what so little sambal oelek would add, but it added a very pleasant warm undertone to the meat. Katjap manis, however it's spelled, is a new ingredient for me. I will need to find other recipes to use it in. However, I have some thoughts on what I would do differently next time. I'd brown in the skillet, but then transfer everything to a pot. The liquid evaporated too quickly in the skillet because of the greater surface area, and the meat was not as tender as I would have liked. I had cut my meat into 1/2 in. cubes, and they were not quite tender enough before the liquid was almost evaporated.
Just let you know, In Indonesia we write ketcjap manis as kecap manis. Ketjap manis is the old Indonesian spelling
