Sprinkle steak with 1/4 teaspoon salt; toss with flour. Heat remaining 1 tablespoon oil in a Dutch oven over medium-high. Add steak; cook 6 minutes. Add spice mixture; cook 1 minute. Stir in tomato paste and molasses; cook 3 minutes. Add remaining 1/2 teaspoon salt, stock, beer, and Worcestershire. Bring to a boil; reduce heat, and simmer 30 minutes.
