Can you eat lambs hooves? My local farm has some sheep that will be slaughtered soon. I'm challenging myself to find recipes (and non-food usages) of every part of their bodies, so that at least we'll not let them rot away.

I've managed to prepare ligaments and tendons for consumption, but I've never tried to eat hooves. Is it possible? Is it part of any existing cuisine?
Hooves are generally not eaten directly but make great soup. If you Google 'trotter soup', you will find recipes from many different culinary traditions, most of them middle-eastern or from the Indian sub-continent.

This page has some typical recipes: http://www.khanapakana.com/recipe-search/s/trotter

Although trotter generally means pig's hooves in the west, it's used to mean any hooves in the east.
