Balut, for those who haven't heard of it, is a duck egg eaten at various stages of embryo development. At 12 days it's like a big yolk, more or less, with the circulatory system forming (lots of veins). But, I have to agree with you...the 18-20 day old, three days from hatching has made more than a few people I knew blow chunks. This is probably more a factor that they had already drank 30 beers or so and ate it on a bet.. but it is pretty gross by western standards. The little beak and feet and soft feathers.....mmmmmmm.
