“Despite the awkward name, this fast and user-friendly wet rub did a fine job flavoring some carne asada I grilled recently (yes, that was redundant). I’m calling it Spanish mustard since I spiked the Dijon with a couple of my favorite ingredients of all time: smoked paprika and sherry vinegar. You can use any thin flap meat (flap steak, skirt steak, round steak) instead of the flank steak.”


  • 1/4 cup sherry vinegar
  • 1/4 cup light olive oil
  • 2 tablespoons Dijon mustard
  • 2 tablespoons smoked paprika

  • 4 cloves garlic, minced (optional)
  • salt and ground black pepper to taste
  • 2 pounds very thin flank steak


Preheat an outdoor grill for high heat, and lightly oil the grate.

Whisk sherry vinegar, olive oil, mustard, paprika, garlic, salt, and pepper together in a large bowl. Place steak in marinade and turn to coat. Marinate at room temperature for 30 minutes.

Cook steak on the preheated grill, turning once, until each side is browned, steak is beginning to firm, and is hot and slightly pink in the center, about 2 minutes per side. An instant-read thermometer inserted into the center should read 140 degrees F (60 degrees C). Transfer steak to a plate and let rest for 5 to 10 minutes before slicing.


Cook’s Note:

  • You can use any thin flap meat, skirt steak, or round steak instead of the flank steak.
