Coconut cream, as opposed to coconut milk, has almost all of the water removed. You can find coconut cream at Trader Joe's, online, and probably at some supermarkets as well. Though most of the water is removed, I still suggest chilling it overnight in order to squeeze that last bit out and get the best results. If you don't have coconut cream close at hand, you can get away with using a can of coconut milk. There will be at bit more water, but not enough to have a major effect on your results.
