- 1 pound bacon, cut into 1 inch pieces
- 2 (15 ounce) cans green beans
- 3 tablespoons all-purpose flour, or as needed
- 2 teaspoons red wine vinegar, or to taste
In a large skillet, cook the bacon over medium heat until almost crisp. Remove bacon pieces, and set aside. Whisk flour into the bacon grease in the pan until it is thick and pasty. More or less flour may be required.
Empty the cans of beans into a large saucepan with their liquid, and add enough water to cover. Bring to a boil, and stir in the bacon and the bacon grease mixture. Reduce heat to low, and simmer for about an hour – the longer, the better. Season with vinegar to taste.
