The cut is generally long and thin, with distinct muscle fibers running through it, which contributes to its chewiness.

- Purpose: Tenderizes the meat while infusing it with umami flavors. The soy sauce also adds saltiness, balancing the natural beef flavor.
- Citrus Herb Marinade
- Ingredients: Fresh lemon or lime juice, olive oil, fresh herbs (parsley, rosemary), garlic, salt, pepper
- Purpose: The citrus helps to tenderize the meat, while the herbs offer a fresh, vibrant flavor.
- Balsamic Vinegar Marinade
- Ingredients: Balsamic vinegar, olive oil, garlic, Dijon mustard, honey
