This Thai dish has one secret ingredient: pig's blood

Boat noodles are a favourite dish in Thailand. They’re made with loads of herbs and spices, plenty of pork, and a secret ingredient: pig’s blood. The blood is used to thicken the broth, but it also adds a rich, umami-like flavour to the dish. Don’t be intimidated — there’s a first time for everything.
