Smother your flank steak in mango sauce!

Flank steak just begs for some super-tasty sauce! I almost always start out by either using a spice rub or marinade on my beef, usually letting it sit and soak in the fridge for the day (or overnight if morning is too rushed). You can find my tips for the basics of grilling flank steak at this post in order to end up with the most tender beef you can. Once it comes off the grill, the real fun starts! This mango sauce is amazing, and you can vary the proportions of ingredients until it is custom-blended for your family.

You can make all the elements of this meal ahead of time if you want, or you could put the sauce together while someone else is grilling the marinated steak. Not counting the marinating time, this is easily a thirty minute meal since it doesn't usually take more than 5 - 10 minutes per side to do a flank steak.

Flank Steak in Mango Sauce

Marinade (for 1-2 lbs of steak):
1/3 c soy sauce
3 T sherry
2 T toasted sesame oil
2 t dry powdered mustard

Mix the marinade ingredients together and divide in half. Stick the steak into a zip-loc bag with half of the marinade ingredients and turn to coat. Save the other half of the marinade for the sauce (below). Keep the steak in the fridge for at least several hours, turning occasionally if you can. If not, don't worry about it!

Mango sauce:
Other half of the marinade
2-3 scallions, sliced thinly
1 T fresh ginger, peeled and grated
1 c of mangoes, either fresh diced, mango salsa (spicier), or mango jelly (sweeter)
Juice from 1 lime

Combine in a small bowl, either ahead of time or while steak is grilling. Serve on the side or slathered over the steak once it's sliced up.
