Question on the preparation of SP after freezing & thawing.

I've been planning on preparing a cactus drink for a friend. The recipe was to use the skin and boil down to shots.

I read somewhere that the more stress adds strength and that extreme temps are best. So, I have a few cuttings and I kept them in the dark for weeks. After that I decided to freeze them and did not realize that the cell walls would burst.....

Can I still use the skin for the prep or would adding all the water from the cactus be a benefit?

Also, not planning on doing this until next week, should I re-freeze them or will they make it for a few days outside in the shade? or will they rot?
