Cut the beef into cubes about 1 inch (3 cm) in size. Peel the onion and chop it finely. Peel and press the garlic.
Salt the meat cubes and mix with garlic.
Heat the lard or oil in a frying pan to a higher temperature and brown the meat in it. The meat will probably release its juices. Cook until the juices evaporate and the meat cubes are golden brown. Stir.
Remove the fried meat and fry the onion in the same fat. If it sticks to the bottom of the pan, add a tablespoon of water. Using a flat spatula, scrape the drippings from the bottom of the pan and stir them into the onions.
Return the beef cubes to the onions, cover with water so that the meat is half submerged. Cover with a lid, turn the heat down to a minimum and simmer until the beef is tender. Stewing time for beef cubes: 2-3 hours.
At the end of the stewing (the meat is already soft and tender), remove the lid, add a little water if necessary and dust the surface of the stew with flour through a sieve. Put the lid back on and let the flour steam for 15 minutes at low heat - do not stir!
Finally, season with salt to taste, stir and serve.
