In a large pot, heat lard on medium-high heat. Add onions. Cook, stirring until they just start to brown, and turn down the heat slightly to avoid burning. Continue cooking until very dark and caramelized—they should be almost but not quite black. Once they reach the right colour, remove the onions to a side plate and reserve.

Add 1 tbsp oil, turn up the heat to medium-high, and then add some of the beef, ensuring the pot isn't overcrowded. Don't touch the beef for about 3 minutes; check to see if dark brown areas have developed. If so, flip the meat until browned on all sides. If not, continue to heat until the right colour is there. Turn up heat if the meat isn't browning enough. Brown the beef in batches, usually two batches does the trick in my pot. Once all of the meat is browned, add both Paprikas and stir over the sizzling heat for about one minute to bring out the flavour of the spices.

Add the onions back into the pot along with the salt and two cups of water (or enough to just cover the meat). Scrape up any bits from the bottom of the pot. Simmer on low for about 1.5 – 2 hours, until meat is tender.

Combine flour and cornstarch with 1/2 cup cold water; stir well to dissolve, pressing out any lumps. Add to the pot with an additional two cups water. Bring to a boil and simmer for about five minutes until sauce is bubbling and thickened. 

Serve over spaetzle style noodles, dumplings or potatoes.
