Cubed Steak with Onion Gravy

Ingredients:

¼ cup flour
¼ cup cornstarch
1 teaspoon ground black pepper
½ teaspoon salt
6 cube steaks
2 tablespoons butter, or as needed
1 cup milk, or to taste
salt and ground black pepper to taste
Instructions:

Step1: Whisk flour, cornstarch, 1 teaspoon black pepper, and 1/2 teaspoon salt together in a shallow bowl. Spread 1 tablespoon of the flour mixture onto a plate; press each cube steak into flour mixture to coat completely.
Step2: Place coated steaks on a work surface and pound each several times with a meat tenderizer on each side to pound flour into steak. Pound each steak a second time to further incorporate flour mixture into the meat.
Step3: Melt butter in a large skillet over medium-high heat until skillet is about 350 degrees F (175 degrees C). Cook steaks in hot butter until browned, 2 to 3 minutes per side. Transfer steaks and any stray pieces of meat to a plate and tent with aluminum foil to keep warm. Let skillet cool briefly.
Step4: Heat the same skillet over low heat. Pour enough milk into the skillet to cover the bottom of the pan. Whisk 1 tablespoon flour mixture into hot milk until gravy has a cream-like consistency, 10 to 15 minutes. Add more flour mixture as necessary to thicken gravy. Transfer any steak scraps back into the skillet and season gravy with salt and black pepper.
Step5: Place hot steaks on plates and top with gravy.
