This is definitely the way. Cut sliced raw liver into strips, put on parchment paper on a tray, put in freezer. A few hours later, take the tray out, cut into desired pill size, then put into frozen storage (I use bags, but you do you). As long as they stay frozen properly, they shouldn't clump together much.

Are they easier to cut after frozen? I would imagine so because before is a slimy mess lol
Yes, much easier. I buy it sliced/frozen from walmart, actually. I use a heavier sharp knife, like a carving knife, with a thicker spine that I can push down on with my free hand.
It will thaw quickly, especially where you cut, so work quickly!
