Mutton offal comes from the mature sheep, and that is the point of this page: halal mutton offal carries a deeper, more assertive flavour than the lamb equivalent. Three cuts are live here, all Certified Halal - mutton liver, mutton kidney and sheep feet, sold as mutton trotters or paya.
Mutton liver is the quick one. It is dense and firm enough to hold its shape on a hot tawa, so slice it thin and give it minutes rather than hours.
Sheep feet work the other way round. They belong in a pot for four hours or more, where connective tissue turns a thin broth into a paya thick enough to set.
Everything is cut to order on the day of dispatch and keeps up to 6 days in the fridge once it reaches you.
