Burger King's new broilers allow it to sell premium burgers

Burger King is cooking up something big for burger fans.

The fast food chain announced the national roll out of its premium Steakhouse XT burger -- with 7 ounces of beef -- that it can now add to the menu because of the state-of-the-art broilers the company installed in most of its U.S. and Canada eateries. The extra-thick steakhouse patty debuts this month.
