I always rinse mine. I either shake the water out, or might pay dry with a paper towel if I feel like it.

I used to bother taking out the blood, but don't think it matters.

I cure my eggs in glass as plastics leach nasties in the eggs. May not make a difference, but I just use gallon glass pickle jars.

Once cured, I transfer them to glass quart jars to freeze or use.
