Place jalapeños directly over the flame of a gas grill. Turn the peppers with tongs to ensure each side is evenly blackened. Remove them from the heat, add them to a metal bowl, and cover with a lid or plastic wrap. You can also place the peppers on a sheet tray under the broiler in the oven until the skin is blackened.
After 5 to 10 minutes, remove the lid or plastic wrap. Use a paring knife or a spoon to peel the skin off of the pepper. Remove the stem as well.
Slice the pepper in half lengthwise. Use a spoon to remove the seeds and membrane. Add the peeled, deseeded, and deveined pepper to the blender.
Add all of the remaining ingredients except for the steak to a high-speed blender or food processor. Blend until smooth.
Place meat in a nonreactive container, like a ceramic pie dish or a large resealable plastic bag.
Pour marinade over the meat and cover. Place in the fridge for 24 to 48 hours. 48 hours is ideal for the strongest flavor.
Remove the steak from the fridge 1 to 2 hours before cooking. Drain and discard the marinade and pat the meat as dry as possible with paper towels.
Set a charcoal or gas grill to high heat. When the grill is hot, spray the grill grates with a bit of nonstick spray or brush the steaks with a tiny bit of oil and place the steaks on the grill (directly over the coals if using charcoal).
Cook until the steaks are seared and reach an internal temperature of 125 degrees Fahrenheit (for medium-rare steak), about 2 to 4 minutes per side.
Remove the steaks from the grill and let them rest for 10 minutes. Thinly slice the meat against the grain on a bias and serve.
Place the grill pan over two burners on high heat. Spray or brush the pan with a bit of oil.
Add the meat to the grill pan once it is hot and cook for 2-4 minutes on each side, until just cooked through. Remove when internal temperature reaches 125 degrees F.
