Blood soup was a delicacy of Zobral's clan, traditionally served with essence of the male, chopped and seasoned.
Captain Jonathan Archer and Commander Tucker were served this soup when visiting Zobral's encampment on the Torothan homeworld in 2152.
Later, while drinking water that Archer had boiled to decontaminate it, Tucker found it to be worse tasting than the soup. (ENT: "Desert Crossing")
In the final draft script of "Desert Crossing", blood soup was instead referred to as "blood of teracaq".
