The “Biscuits’ Best Friend” Sawmill Gravy

The Brown: In a large cast-iron skillet over medium-high heat, brown the sausage. Use a wooden spoon to crumble it into very small pieces.
The Fat Check: Once the sausage is cooked through, do not drain it yet. You need about ¼ cup of fat in the pan. If there’s too much, spoon some out; if there’s not enough, melt in a knob of butter.
The Roux: Sprinkle the flour directly over the sausage and fat. Stir constantly for about 2 minutes. The flour should coat the meat and turn a light “sandy” color. You’re looking for a nutty aroma, not a dark brown color.
The Slow Pour: Lower the heat to medium. Gradually pour in the milk, whisking or stirring constantly. Start with 3 cups—you can add more later to adjust the thickness.
The Thickening: Continue to cook and stir until the gravy comes to a gentle simmer. It will thicken significantly as it heats up.
The Seasoning: Stir in the heavy black pepper and salt. Taste it! Sawmill gravy needs a lot of pepper to cut through the richness of the dairy.
The Finish: If the gravy gets too thick (it should coat the back of a spoon), splash in a little more milk. Serve immediately while it’s steaming hot.

Don’t Drain the Flavor: Those browned bits stuck to the bottom of the pan (the fond) are what make the gravy savory. The milk and flour will lift them up and incorporate them.
Whisk Like You Mean It: If you see lumps, don’t panic. Just keep whisking vigorously as the milk heats up; they will usually smooth out.
The “Cooling” Factor: Gravy thickens as it sits. If you aren’t serving it the second it’s done, keep it on low heat and keep a little extra milk nearby to thin it out before plating.
