In a medium sauce pan over medium high heat, saute the garlic cloves until aromatic. Add the liquids, spices, chipotle peppers, zest, lemon and lime juice. Bring everything to a boil. Turn the heat down and simmer for a few minutes to marry all of the flavors. Blend until smooth and let cool. Pour marinade over the steak and let stand in the refrigerator for a minimum of 8 hours. 24 hours is preferred.
