Ok, after I cut the recipe in half, marinated the beef all day, and then cooked it a little while ago, here's the results:
I used a round steak that I had cut into cubes. I drained the marinade (so I thought), and poured the beef into a piping-hot cast iron skillet that I had put some oil into. Obviously, I didn't get all the marinade out, as I had to pour the liquid out to get the beef to caramelize. Also, after the beef had browned, and I poured in the marinade to reduce it into a sauce, I realized I had way to much oil in the pan. I'm going to reduce the amount of oil I use in the marinade next time, and probably won't add quite so much to the pan (I had an oddly-shaped bottle of oil, and it's almost full, so it's hard to control right now).
It's good. It's also different. I might add more cumin and chili powder to the marinade as well.
Peace, Love, and Vegetable Rights!
