In a large roasting pan place brisket fat side up. Whisk together broth, soy sauce, lime zest, lime juice and garlic cloves. Pour over brisket, cover tightly and place in fridge overnight. (24 hours if possible)

Braise brisket in a 300 degree pre-heated oven for 4 – 4 1/2 hours or until fork tender. Uncover, carefully remove brisket to a serving platter, tent with foil and allow to rest for 20 minutes.

Place roasting pan on stove top over medium high heat and cook marinade/juices until reduced in half.

Cut brisket across the grain or cut brisket into large pieces, and shred with two forks. Serve warm with pan sauce.
