The sauce's yellow colour comes from potash (akanwu) dissolved in water and stirred into palm oil, which emulsifies the oil into a thick, pale paste.
Nkwobi is chunks of tender cow foot simmered until soft, then tossed in a thick, spicy sauce of palm oil, potash, ground calabash nutmeg, and utazi leaves, traditionally served in a wooden bowl. It's a fixture of Igbo bars and joints, eaten by hand and shared over drinks.
