Put all the ingredients (except the water) into a high speed blender or a small food processor. Pulse the blender for about 20 seconds or so and check out the consistency of the peanut sauce.
Add some warm water, 2 tablespoon at a time and blending each time until it gets to the consistency you want. More water=thinner peanut sauce.
Serve or keep in fridge for up to 3 days.
