Sweet Beef

In a large heavy-bottomed pot or Dutch oven, heat bacon drippings or vegetable oil over medium heat until shimmering. Add butter and allow it to melt completely into the fat base.

Add the brown sugar to the pot and stir continuously until it dissolves and begins to caramelize slightly in the fat, creating a rich, sweet base.

Stir in the chili sauce and mustard, combining them thoroughly with the sweet fat base to build the soup's signature sweet-savory flavor.

Add the beef to the pot and stir to coat it well with the sauce mixture. Cook over medium-high heat until the beef is browned on all sides.

Pour in the water and add salt, then bring the mixture to a boil while stirring to deglaze any browned bits from the bottom of the pot.

Stir in the vinegar to balance the sweetness of the brown sugar and chili sauce, adjusting the amount to taste for the desired sweet-sour balance.

Reduce heat to low, cover the pot, and allow the soup to simmer gently until the beef is fork-tender and the flavors have melded together.

Taste and adjust seasoning with additional salt, vinegar, or brown sugar as needed, then ladle into bowls and serve hot.
