I recognize that virtually all of you have been doing this longer than I have, so I'm going to just throw this question out here in the hope that someone's already figured this out.

Two of my three T. marcianus will readily consume pinkies, the third is well on his way, so I've begun raising mice myself to lower the cost of feeding they and whatever else I collect along the way.

My question is: What is the best method for storing euthanized pinkies that keeps them fresh and edible when thawed? I've considered open air freezing, submersion in water to freeze, and just about everything in between, but what works best in your experience?
