Key West Flank Steak

My husband, Jason, is the cook in our family. This is his recipe, inspired by his Colombian roots and our visits to Key West. Sometimes we grill extra lime and onion slices alongside. Serve with sides of rice and fried plantains. —Gretchen Ospina, Columbia Heights, Minnesota

    The quantities listed for the marinade are way off. One cup of cilantro with less than a cup of liquids? The cilantro absorbs all the liquids and you have a cilantro paste with red onions. I bought a bag of key limes and used all but 6 for the juice. The other 6 were halved and put in with rest of marinade as instructed. There was about 1/2 cup key lime juice and I used it all, 1/2 cup white wine vinegar, and 1/3 cup olive oil. I used about a 1/2 Tbsp or more of cilantro. I used 1 small red onion. My steak is marinating now, can’t wait to try it, mouth is watering.

    Amazing lime flavor. The key limes really add a great flavor, something a regular lime won't.
