Kidney, ox

Ox kidney is the edible kidney of a mature bovine animal, generally sold whole or cut into portions. It may be trimmed and sliced for frying or grilling, or cooked more slowly in braises and other savoury preparations. Preparation often removes the central fatty and connective tissue, which can affect the edible yield and eating texture.

The raw organ is dark reddish-brown, firm and distinctly lobed, with a dense texture. Its savoury, characteristic organ-meat flavour can be pronounced. It is available fresh or frozen and may be sold already trimmed or cut; these forms are not interchangeable when judging preparation time or edible portion.
