Step #2 Roast coriander & cumin seeds in a fry pan over low heat/flame until fragrant, cool, & grind coarsely in a mortar or a spice grinder.
Step #3 Combine beef & the rest of the ingredients & marinade 1 hr.
Step #4 Place beef pieces on a cake rack sprayed with Pam & put the rack in a foil wrap lined cookie sheet large enough to catch any liquid dripping from the beef.
