Chop the coconuts into small pieces and grind it with small amount of water in a blender. Use very small quantities at a time and use can filter it using a tea strainer. Use can chop them up and freeze them as well, so can be used at a later date.
I bought 2 coconuts reduced to clear and now don't know what to do with them! Will use the flesh from one to make some ice cream but don't know what to do with the rest? Do like a coconut based curry but not sure how to substitute tinned coconut milk for real stuff?
