Feet

feet of animals consist mainly of skin, bones, and cartilage, but are normally edible in that they yield some meat. Also, in most instances, they provide gelatin when boiled; boiling calves’ feet in particular used to be an essential step in making a jelly.

In many cultures feet are not seen as repulsive or unsuitable to eat, but in the English-speaking world there has been a tendency, especially in recent times and urban environments, to disdain them unless they are disguised in some way (e.g. appearing in a brawn) or bear some other name (e.g. trotters), perhaps with a traditional ring to it (e.g. cow-heel).
