Soup Number Five, variously spelled
Soup No. 5 or Soup #5, is a
soup made from bull's testicles[1][2]
or penis.[3]
The dish originates from
Filipino cuisine.
It is believed to have aphrodisiac
properties.[3]
Beef penis and testicles are washed and cleaned, then scalded in
boiling water. The genitalia are then cut into
pieces and set aside. Various other ingredients such as pork or chicken, ginger, and vegetables are
combined in a stock pot with the beef penis and testicles, covered
with enough water and simmered until tender. It is
then seasoned with salt or pepper and served hot.
