You can check if the loaf is done by sticking a chopstick into it and pulling it out again. If there is no residue on the chopstick your liver meatloaf / liver bread is finished.
This recipe is very basic and you can modify it by adding ground beef, a diced onion, a minced avocado(minced in food processor before adding the liver) or some shredded cheese that you stir in with a spoon after mincing everything.
For a liver pudding, simply add a tablespoon of butter, 100g heavy cream & 250g ground pork/beef to the mixture and 2-3 bay leaves on top, before putting it into the oven.
Another idea would be to bake the mixture for about 20-30 minutes on a baking tray and using it as a pizza crust.
I simply added some mustard, low carb ketchup and cheese. If you want to you can go all the way to make sandwiches with the liver bread, with salad, cucumber, bacon, cheese and a fried egg – or whatever you prefer.
