"When they feast a friend they kill an ox, and set immediately a quarter of him raw upon the table (for their most elegant treat is raw beef newly killed) with pepper and salt; the gall of the ox serves them for oil and vinegar; some, to heighten the delicacy of the entertainment, add a kind of sauce, which they call manta, made of what they take out of the guts of the ox; this they set on the fire, with butter, salt, pepper, and onion."
