I'm making blood sausage again. Since I don't want to bother with sausage casings again, I'm trying a meatloaf-like version.
5 cups blood
7 eggs
1/2 cup milk
13.5 oz (1 can) coconut milk
1 pound pig brain
2 cups Textured Vegetable Protein (I'd have used more but I forgot to get a new bag last time I was out)
4 cups flour (I used a mix of corn masa and rice flour, which is what I had on hand)
2 yellow onions and 1/2 cup ginger, minced and sauteed
1 tsp salt
Vast quantities of garlic and black pepper
Potato flakes (buy the largest box available)
Combine all ingredients in a giant bowl. Stir. The amount of potato flakes you'll need is just enough to get it to a very thick, lumpy consistency. It should be just a bit thinner than bread dough, but much chunkier. The brains should break up into little pieces as you stir, if it's thick enough. Spoon all of that into a couple of cake pans, cook at 325 degrees for an hour. 10 minutes in, you may wish to apply a sauce, as I have done (mine was sauerkraut juice, mustard, sriracha, and a little sugar). Completely fills 2 rectangular cake pans, though I don't know the size.
I made this up on the spot, so it's a bit experimental. Depending on where you get your blood, it may have clotted already - don't worry, just shove it in a blender with some of the other liquid ingredients. You can probably omit the milk, which I only added for that exact purpose. Substituting grain for flour would also not be a bad strategy, it's just something I forgot to buy. You can also substitute suet or chunks of meat for the brain. It did clot again while I was mixing, thickening things rather dramatically, but I hear that can be avoided with vinegar if you prefer to let it do its thickening as it cooks, which you probably do if you're using grain (since you want it wet enough for that to absorb a lot of liquid as it cooks, but you want it solid by the end of it).
EDIT: Okay, so use cake pans, not loaf pans. The loaf pan took about an hour longer to cook and is far too dry on the exterior. I would not recommend this recipe as-is. It needs more TVP, less potato, and no flour at all (oatmeal instead). More black pepper, as well.
