🔑 Key Takeaways
- Cut flap steak to 1‑1.5 inches thick for optimal tenderness and grillability.
- Always slice against the grain to break up long muscle fibers and keep the steak juicy.
- Trim excess fat if you prefer a leaner cut, but leave a small fat cap for extra flavor during cooking.
- Use a balanced acid‑based marinade (vinegar or citrus) with oil and herbs to tenderize without over‑softening.
- Grill on high heat for 3–4 min per side for medium‑rare; flip only once to lock in juices.
- Stir‑fry flap steak thinly; the quick, high‑heat cook preserves its delicate texture.
- Store leftovers in an airtight container in the fridge for up to 3 days or freeze for up to 2 months.
