Don’t expect something sweet and muffiny here. We follow the three tenets of traditional Southern cornbread: There’s no sugar added, there’s no flour (only course-ground cornmeal), and there’s no better way to bake it than in a cast-iron skillet. This rustic cornbread is sturdy and dry and meant to be dunked, like say in this beef chili. Serve it with this hot honey butter. See more Super Bowl recipes here.
Preheat oven to 375°. Set dry skillet over low heat to heat while you make the batter. Whisk cornmeal, baking soda, and salt in a medium bowl. Make a well in the center and add egg and buttermilk, then whisk vigorously, starting in the center to incorporate egg and working your way out, until dry ingredients are incorporated and batter is smooth.
Increase heat to medium-high and add bacon fat to skillet. Swirl to coat bottom and sides of skillet. Whisk batter once more to reincorporate, then pour into skillet and smooth top (batter will sputter around edges).
Bake cornbread in oven until the edges are golden brown and the top is golden, cracked in places, and firm to the touch, 25–30 minutes. Let cool in pan at least 5 minutes before cutting into wedges. Serve with Hot Honey Butter.
Do Ahead: Cornbread can be baked 8 hours ahead. Let cool; store tightly wrapped at room temperature.
