A very small amount of cocoa powder will have been processed to contain lecithin. Unless you've specifically asked for it, yours is not.
Why do you read that? i've no idea 8) i've read lots of crazy things on the internet.
One t hing you'll need to watch with higher fat powders is that they will be more susceptible to both temperature and pressure, in that the fat in them may melt or squeeze out, and when it resolidifies, will turn yoru bag of nice powder into a brick of solid cocoa. however, it's still fine, it's just needs to be reground.
