Yeah, at the store there was this little pamphlet near the cart for these things, and it said that you have to 'score them, remove the top bottom and sides' and then 'break them apart underwater. The seeds will go to the bottom and the membrane will float to the top". Thats bullshit, I tried this and its actually harder to separate than just peeling and doing it in a bowl. Plus, it takes so long that your hands get all raisin-ey from the water.
I just score around the midline with a knife, then kinda twist laterally until the two halves pop apart. Then its just pick and peel, white goes in one bowl, red in another. A small cup of water is needed to keep those fingers from sticking up the keyboard and mouse when I'm at my computer.
