Yes, I ate it. I'm not a big fan of blood products, and when confronted with a full English breakfast I'll chuck the blood pudding. Duck blood tofu, on the other hand, is something that I'll put in my mouth. It was mild--I wouldn't have known to be grossed out if my friend Kate hadn't gagged while I ate it.
This is just a piece of beef, but doesn't it look tasty? This was an expensive, high-quality hotpot place in Beijing near Zhichunlu.
