/ck/ - Food & Cooking

Hey guys, I'm working on a strange project that involves feeding blood to mosquitoes, and I don't want to hassle you with the details, but I need to make something like the blood sausages in pic related but uncooked, nothing except for blood inside it, and I need it to stay fresh and clot-free for as long and as cheaply as possible in a constantly body-warm condition.

I tried /sci/'s sqt for preservative suggestions but they drew a blank and just asked about my motivations. I'm sure you guys are much more savvy when it comes to preserving food, and hopefully a little less inquisitive.
