Ingredients

Method

Combine brown sugar, chile powder, paprika, salt, pepper, cayenne, granulated garlic, mustard powder, coriander, and cumin in a small bowl.

Prepare a grill for medium-high heat; oil grate. Grill corn, turning occasionally, until lightly browned all over, 8–10 minutes; let cool. Cut kernels from cobs and place in a medium bowl. Add onion, jalapeño, tomatoes, cilantro, and lime juice to corn and toss to combine; season with salt and pepper. Set salsa aside.

Meanwhile, coat steak with all of dry rub, packing on more than once if needed, and drizzle with 2 tablespoons oil to help rub adhere. Grill steak, turning occasionally and moving to a cooler spot on grill as needed to control flare-ups, until nicely browned and an instant-read thermometer inserted into the thickest part registers 130°F, about 4 minutes per side for medium-rare. Transfer to a cutting board and let rest 10 minutes.

Return steak to grill just to recrisp exterior, about 1 minute per side. Transfer back to cutting board and slice against the grain. Serve topped with salsa.

Salsa can be made 1 day ahead. Cover and chill.
