Get one, write down a B or a W, eat it, get the next one. Repeat until nauseous. It's much faster than flipping a coin, and less boring

But of course there probably isn't an even number of blacks and whites in the bag, and with each one you eat you reduce the odds of that color appearing again. So overall a bad system.

When in doubt, you could of course apply the system where BW means B, WB means W, and BB or WW means ignore, but that means you'll have to eat at least 3 times more candy.
You should also put the candies back into the bag after randomly drawing them and writing down B / W.
