Season the minced meat with a little salt and pepper. Shape into small balls and fry nicely all around in a large roasting pan. Take out the dumplings and sauté the onions cut in half rings in the frying fat until golden. Add the dumplings again and top up with the beer and ketchup. I rinse the bottle of ketchup a little more with water and add that too. Then add enough paprika powder (should taste nice and hot. Let simmer for about 30 minutes.
