Mix chili powders, cumin, and oregano in small bowl and stir in 1/2 cup water to form thick paste; set aside. Toss beef cubes with salt; set aside. 2. Fry bacon in large, heavy soup kettle or Dutch oven over medium-low heat until fat renders and bacon crisps, about 10 minutes. Remove bacon with slotted spoon to paper towel-lined plate, pour all but 2 teaspoons fat from pot into small bowl; set aside.

Reduce heat to medium, add 3 tablespoons bacon fat to now-empty pan. Add onion; saut until softened, 5 to 6 minutes. Add garlic and jalapeo; saut until fragrant, about 1 minute. Add chili paste; saut until fragrant, 2 to 3 minutes. Add reserved bacon and browned beef, crushed tomatoes or tomato sauce, lime juice, and 7 cups water; bring to simmer. Continue to cook at a steady simmer until meat is tender and juices are dark, rich, and starting to thicken, about 2 hours. 3. Mix masa harina with 2/3 cup water (or cornstarch with 3 tablespoons water) in a small bowl to form smooth paste. Increase heat to medium; stir in paste and simmer until thickened, 5 to 10 minutes. Adjust seasoning generously with salt and ground black pepper. Serve immediately, or preferably, cool slightly, cover, and refrigerate overnight or for up to 5 days. Reheat before serving.
