Ahhh, even if it wasn't an Ohio recipe, I would dig this.
Rich tomato sauce infused with cider vinegar clings tightly to deeply browned meat fibers while tender aromatics melt into a savory pan gravy. Flank steak contains substantial connective tissue that requires careful thermal management, transforming tough muscle into yieldable slices when braised low and slow.
Reheating leftover slices gently in a covered skillet with two tablespoons of water prevents the lean beef from drying out. Slicing the chilled meat perpendicular to the muscle fibers ensures a tender bite every single time.
