Chop it up into small pieces and when cool put the pieces into a number of airtight bags and store in the fridge. Use liver pieces as treats when training) Scones: Sift flour and salt into a bowl, rub in butter. Add chopped liver. Use a knife to stir in milk and enough water to mix to a sticky dough. Turn dough onto lightly floured surface, knead quickly and lightly until dough is smooth. Press dough out evenly to about 2 cm and cut into rounds.
