Instructions
Cut the beef into roughly 1 ½ in cubes.
Mix together the remaining ingredients in a non-reactive bowl and add the beef chunks. Cover and refrigerate overnight, or at least a few hours.
When ready to grill, thread the beef cubes onto skewers. Preheat your grill to medium-high heat (you should be able to hold you hand a few inches from the grates for 4-6 seconds). Cook the kebabs until the beef is cooked through (slightly pink is fine), turning as needed to cook evenly.
Notes
These skewers are often served with some very finely chopped onion mixed in with aji amarillo and a little salt to make a kind of spicy relish on the side.
