Flank Steak With Lime Marinade

In a resealable plastic bag, combine lime juice, soy sauce, scallions, ginger, and red-pepper flakes. Add the steak, seal the bag (place it in a dish to catch any leaks), and marinate in the refrigerator, turning occasionally, for at least 1 hour and up to 6 hours.

Heat grill to high; lightly oil grates. Remove steak from marinade, letting excess drip off, then scrape off any bits of scallion and ginger and pat steak dry (discard marinade); season with salt and black pepper.

Place on grill; cover. Cook, turning once, until meat reaches desired doneness, 6 to 8 minutes for medium-rare.

Let steak rest 10 minutes before slicing thinly against the grain.
