Mix the ingredients thoroughly in a bowl or gallon-sized food storage bag. Use an immersion mixer if you have one to get the best possible mix.
Pour the marinade into a food storage container or keep it in the bag. Add the steaks, ensuring the liquid covers all of the meat. If you can’t cover both sides of the steaks, make sure to flip the meat at least once for even exposure.
Let the meat marinate for 1 to 24 hours. Longer marinating periods lead to a stronger flavor and more tender texture.
