This Is The Recipe That We Use To Make
Birthday Cakes For All The Polarspirit Pack

1 lb Liver (liquidized)
1 lb Plain Flour
1 Egg
1 Clove Garlic

Mix all together well, adding a little water as necessary to be able to
pour the mixture into a large cake tin.
Place in the oven on a medium heat for approximately 45 minutes.
Push a skewer into the centre to test if the cake is thoroughly cooked. If the skewer comes out clean, it is ready.
Allow to cool
If you wish add some cooked sausages to act as the appropriate number of birthday candles
Serve to some very happy Doggies!
