What herb or spice is the Grilled Prime Sirloin rubbed with?

The Grilled Prime Sirloin is specifically rubbed with coffee, which adds a unique and rich flavor profile to the meat. Coffee as a seasoning is known for enhancing the natural flavors of beef, providing a depth and slight bitterness that balances well with the savory elements of the dish. This technique not only contributes to the overall taste but also creates a beautiful crust during the grilling process, which enhances the texture and visual appeal of the steak.

The other options, while they are common seasonings used in various dishes, do not specifically pertain to the signature preparation of the Grilled Prime Sirloin at Cooper's Hawk. Garlic and paprika might contribute flavors that could complement a steak, but they are not the defining rub used in this particular preparation. Cayenne pepper adds heat, making it more suitable for dishes seeking spiciness rather than the deep and rich flavor characteristic of a coffee rub.
