Heat beef tallow in a cast iron pan over medium-high heat.
Dip tenderloin pieces in half & half, then roll in flour mixture. Place meat carefully in hot fat.
Fry meat 1 or 2 minutes on each side, or until an instant read thermometer reads 145.
Remove from pan and place on several layers of paper towel to drain. Serve hot.
Notes
Use your favorite steak seasoning to mix with the flour. If you don't have a premade blend, try using: 1 teaspoon salt, 1 teaspoon black pepper, 1/2 teaspoon garlic, 1/2 teaspoon onion salt, 1/2 teaspoon lemon/pepper. You can use all-purpose flour, OR if gluten sensitive, you can use an all-purpose GF blend and it works just fine! Use any venison steak you prefer. Elk tenderloin, backstrap, etc.
