Actually I scrape the outer layer before chopping to prevent the black layer getting in. If its a tender coconut, you can actually remove a thin layer and you will get a pure white. coconut for milk. But with mature ones, on scraping the brown outer part will peel off. If you check out the pieces you find it brown and while in most places! And also when its mature one and after pulsing it, the brown part stays back after running it through a sieve.
Thanks to my blogger friends for sharing their tips, I am sure its going to be very useful. Though grating it sounds a tough job as I can't grate a coconut for nuts!!.
If you are using coconut this is not so mature or thick, within few minutes in the mixie yields good amount. But if its really thick, you got to run it few times more to get the milk.
Wash and chop the coconut into smaller pieces.
First run them in the mixie for couple of rounds, then add required water and pulse it again.
Strain it over the sieve. Thick milk will fall down. Press firmly so that you get most of it out.
Pulse it again with more water to get thinner milk, which can go into any gravy that you planned.
