Behold my lunch today: black pudding, a.k.a. morcilla.
A.k.a. boudin noir. A.k.a. blood sausage.
I ate it and I LOVED it. I used to eat it when I was a kid and didn't know I was eating rice soaked in pig's blood, really. So now that I know, I try not to think about it and instead enjoy the deliciousness that is.
Overthinking is the enemy.
Although if you over-overthink, you realize that if you eat any kind of animal, you're eating blood by default just because there is no way you can remove every single blood cell from every single microscopic capillary in your dinner.
But yes, I realize that most people don't think about eating blood as something good, or even remotely sane. But oh…. you have no idea of what you're missing. Especially when that something is a bridge to a small part of your cultural identity.
And especially when that something can connect you to yourself AND gross people out.
The inner twelve-year old never evolves, after all.
A Daily Dose of Zen Sarcasm! 
What, did you run out of haggis?
Not just blood. People eat sinew all the time, too. 🙂
OMG! i’d always heard of boudin growing up but never knew what it was. you’re right, some things, you’re just better off being ignorant about – ha ha.
