What type of cooking technique is prominent at Saltgrass?

The prominent cooking technique at Saltgrass is charbroiling and grilling. This method is fundamental to the restaurant's focus on delivering high-quality steaks and grilled items, which are signature offerings on the menu. Charbroiling involves cooking over direct heat, producing distinct grill marks and a pleasing char while retaining the natural flavors and juices of the meat. Grilling enhances this further by allowing for a variety of temperature zones, making it easier to achieve different levels of doneness as well as depth of flavor. This technique aligns with Saltgrass's emphasis on a robust, smoky flavor profile and creates a unique dining experience that reflects traditional Texas cuisine.

The other options, while they may involve cooking techniques used in various culinary contexts, do not characterize the essence of Saltgrass's menu, which is centered around grill and charbroiled dishes, particularly their steaks.
