If in doubt about using wheat flour, replace with potato flour.
8 oz liver, any type
4 oz flour
1 tbsp oil
2 eggs and shells
2 cloves garlic
Blitz everything together in a food blender until it is a smooth batter, pour into either a swiss roll tin, or 2 sandwich tins, bake at Gas 4 for about 30 mins, should be firm to the touch when ready. cut into small pieces, and freeze what you dont need.
