Place the freshly scraped coconut from one coconut in a large bowl and add 185 ml (6 fl oz/¾ cup) cold water (or coconut water) and stir to combine. Take a handful of the coconut scrapings and squeeze hard, releasing the liquid back into the bowl. Return the squeezed coconut scrapings back to the bowl and stir to combine. Repeat the process until you have extracted about 125 ml (4 fl oz/½ cup) of thick and creamy liquid (coconut cream). Strain through a fine sieve into another bowl and set aside. Empty the contents of the sieve back into the first bowl so you can re-use the scrapings to extract the coconut milk.
