Top blade roast, a shoulder cut with great flavor, has a pesky line of gristle that runs horizontally through the center. Follow these simple steps to remove it and cut perfect Swiss steaks. 1. Place roast on cutting board and cut crosswise into four even pieces. 2. One piece at a time, turn meat on its side to expose the line of gristle that runs through its center. 3. Remove by slicing through meat on either side of gristle to yield two "steaks." Repeat with remaining pieces of blade roast to yield a total of eight steaks. 1. BUTCHER ROAST Adjust oven rack to middle position and heat oven to 300 degrees. Following photos at left, cut roast crosswise into quarters and remove line of gristle to yield 8 steaks. 2. BROWN STEAKS Pat steaks dry with paper towels and season with salt and pepper. Heat 1 tablespoon oil in Dutch oven over medium-high heat just until smoking. Brown 4 steaks, about 3 minutes per side. Transfer to plate and repeat with remaining oil and steaks. 3. ADD AROMATICS Add onion to empty pot and cook until softened, about 5 minutes. Add garlic, thyme, tomato paste, and flour and cook until fragrant, about 1 minute. Stir in diced tomatoes and broth and bring to boil. 4. BRAISE STEAKS Return steaks and any accumulated juices to pan. Transfer to oven and braise, covered, until steaks are fork-tender, about 2 hours. Transfer steaks to platter, tent with foil, and let rest 5 minutes. Skim fat from sauce. Stir in sun-dried tomatoes and parsley. Season with salt and pepper. Pour sauce over steaks. Serve.
