Searing the steaks in a very hot, dry pan ensures succulent meat.
Combine broth, gin, vinegar and juniper berries in a measuring cup. Set aside.
Brush or rub steaks with oil. Press pepper onto the steaks and season with salt. Heat a medium cast-iron or heavy skillet over high heat until nearly smoking. Place steaks in the heated pan and cook until browned on the outside but still pink inside, 2 to 3 minutes per side. Transfer steaks to a plate and keep warm.
Add the reserved broth mixture to the pan and cook over medium heat, stirring to scrape up any brown bits on the bottom of the pan, until reduced slightly, 1 to 2 minutes. Place the steaks on individual plates and spoon the sauce over.
To crush juniper berries: Place whole spices in a plastic bag and crush with the bottom of a heavy skillet or pulse in a spice grinder.
