don't you be talking about my sisters like that.....
mags has answered it.
two wonderful variations - try, if you ever get the chance, Agneau de Sel - lambs are taken off the mountain and fed estuary sea grasses and a slight background salty flavour adding to the meat - delish. Though French, they practice it off Cross Fell and down onto the Solway Firth.....well worth keeping a look out for.
The other is more controversial - Agneau du lait........lambs fed solely on milk, the meat white and succulent - a version of what veal is, though the lambs aren't force fed, just not permitted solids.
