lamb fat
White fat from lamb, for example from the back, around the kidneys or from the tail; once rendered, it tastes distinctly of lamb.
Lamb fat is available from butchers, especially Turkish, Middle Eastern or halal butchers, often on request or as trimmings from fatty cuts. You can also render it yourself from fatty lamb.
Substitute:
Ghee provides the richness and browning but not the characteristic lamb flavour; in minced meat mixtures, fattier minced lamb can be used instead.
