Grilled Balsamic-and-Garlic Flank Steak

It is much better if marinated in a zip lock back for 2+ hours in the fridge. Also, I made it in a Cosori air fryer (countertop convection oven with a fancy name). Eight minutes in the "steak" setting and it was perfectly done.

Okay because couldn't taste any marinade really at all! Used a sirloin steak and the meat was fine and tasty as a sirloin steak is. Marinated for 15 minutes: 1 lb steak with 1/2 the marinade. If I were to try again I would use full amount for our usual steak and marinate it for 45 minutes to see if there is any flavour. The recommended wine was lovely.
