Using ox or pigs liver gives the best results.
Place the uncooked liver on a baking tray – sprinkle with Garlic powder (not garlic salt)
Place in the oven at 180 degrees and cook till ‘dry’ – then cut into small pieces add more garlic powder – return to oven and cook slowly – till the liver is hard all the way through.
Let cool, and when cold can be bagged and will keep for weeks.
Can be cooked in a Pyrex dish in a microwave oven - with CARE
