It is an "edgy, almost forbidden" ingredient that could make the bravest of cooks turn the colour of the traditional chef's uniform... white. Despite blood being the clearest "brute fact" that animals have been slaughtered to put food on a plate before us, one of the world's top culinary teams is calling for blood to be used more widely in the everyday food we eat.
The Nordic Food Lab says blood is nutritious, delicious and could be the solution to the growing problem of egg allergies. The Copenhagen-based lab has become an innovator in culinary science since it was created in 2008 by the Danish chef René Redzepi, the man behind Noma, three-time winner of the best restaurant in the world title.
Blood has similar properties to eggs in cooking and also is a good source of iron, Elizabeth Paul of the Food Lab said.
"Blood has become somehow edgy, almost forbidden, yet it has been used as food for as long as animals have been killed and eaten. It is elemental, both mystical and mundane. And it makes us damn curious in the kitchen."
They believe it is a natural replacement for egg whites and should used more widely now that eggs are Europe's second most common food allergy. The lab had successfully experimented in substituting blood for eggs in cakes, meringues, pancakes and ice cream, among other sweet dishes.
