Balsamic Whiskey Cream Sauce
In a Ziploc bag or bowl, add steak, coffee rub and sea salt. Shake or stir steak with seasoning until coated evenly. Let rest at room temperature for 10-20 minutes while you make the sauce.
To make the sauce, heat 2 Tbsp oil in a large sauté pan. Add the onions, season with salt, and cook until soft and slightly caramelized, about 10 minutes. Add the whiskey and vinegar, stir. Add the cream and cook for another 1-2 minutes. Remove from the pan and keep warm until ready to serve.
Add the remaining 2 Tbsp oil to the pan. Once hot, add the seasoned steak and sear, turning to cook all sides, about 3-4 minutes total (3 minutes for medium rare.)
