Tip to separating leaves: Slice off core, not cutting too much in that it ruins the good leaves after removing the outer 2-3 yucky ones. See which leaf is top and first to remove, slice through that leaf at stem and gently pry open a bit. Wherever there is resistance, run under hot water to soften and leaves will fall and pull away easily. Take your time doing this with each leaf and they'll all be picture-perfect and not tear. Doesn't take long, either.
