Otherwise Disgusting Foods (ODF)

[grue]

I can think of three traditional portuguese dishes that are delicious and literally made with blood

chicken blood (Cabidela)
pork blood (Sarrabulho)
lamprey blood (Lampreia)

The latter is delicious but absolutely disgusting. Not many people pull it off, it's a hard dissh to cook. My mother makes it once a year and I eat it but it takes mental discipline to switch off the fact that you're literally eating blood.
