Peeling coconut meat from shell I roasted these two coconuts at 350℉ for about 15 min. 

I was hoping it would make it easier to detach the meat from the shell but it didn't so much. I peeled it but I struggled with a butter knife. Is there a way to cook it differently to make it easier to peel or is there a better tool than a butter knife?
Cross-hatch it several times with a sharp knife (every 2-3 cm or 1 inch).  Then you can pry up the chunks more easily.
