Step 1

Place steak in a large bowl. Knead sugar into meat to form a thick crust. Cover the bowl with plastic wrap and let sit at room temperature; 3 to 4 hours.

Step 2

Preheat an outdoor grill for high heat, and lightly oil the grate.

Step 3

Cook steak on preheated grill until each side is caramelized, about 10 minutes per side.

Step 4

Preheat oven to 350 degrees F (175 degrees C). Line a baking sheet with aluminum foil; place steak on prepared baking sheet.

Step 5

Roast in the preheated oven until steak is starting to firm and is reddish-pink and juicy in the center, about 20 minutes per side. An instant-read thermometer inserted into the center should read 130 degrees F (54 degrees C). Remove from oven and let rest for 15 minutes before slicing.
