It doesn't really thicken unfortunately which is why it's more of a laksa kind of thing. It still tastes nice though, you can boil it down a bit so there is less of the soupy-juices but It doesn't go thick.
Unless you blended the spinach? Hmm I wonder if that would work to create the illusion it was thicker ?
