Sauté the onion, the TV Paprika and a good pinch of salt in 1 tbsp of pork fat until the onion is translucent and the TV Paprika has started to soften.
Add the pork liver, and fry for 5 minutes, adding a little water if the mixture starts to stick.
The the pan off the heat and add the tomatoes, sweet Hungarian paprika, pepper, and marjoram and enough water to half cover the water, and stir well.
Then put back in the heat and bring to a gentle simmer.
Add the pig brains, and cook for 3-4 minutes. Then adjust the seasoning and serve with crusty bread.
