In a large pot, melt the vegetable shortening over medium heat.

Add the beef stew meat and cook for 5-7 minutes, stirring occasionally, until browned.

Stir in the powdered black pepper, salt, paprika, minced garlic, and sliced onions.

Cook for an additional 5 minutes.

Pour in the steak sauce and 2 cups of water, stirring well to coat the beef evenly.

Reduce the heat to low and let the mixture simmer for 15 minutes, or until the meat is tender, stirring occasionally.

In a small bowl, whisk together the all-purpose flour and 2 tablespoons of water until smooth.

Gradually add this mixture to the simmering meat, stirring continuously.

Continue to simmer for an additional 2-3 minutes, allowing the stew to slightly thicken.

Serve the Ukrainian beef goulash hot over cooked pasta or egg noodles, with a dollop of sour cream on top, if desired.
