There is something deeply satisfying about a loaf of bread that comes together with just four ingredients and no yeast, no proofing, and no fuss. The cold buttermilk reacts with the baking soda to give this loaf its lift, producing a dense yet tender crumb with a beautifully crackled, golden crust. That iconic cross scored across the top isn't just for looks — it helps the heat reach the center so every slice bakes through evenly. For anyone navigating mustard sensitivities, store-bought breads and even artisan loaves can be a minefield of hidden seasonings and shared production lines, but this one is refreshingly straightforward. Every ingredient is right there in plain sight: flour, baking soda, salt, and buttermilk — nothing tucked away in a spice blend or glaze. Baking it in a preheated cast iron skillet gives the bottom an extra-crisp finish that rivals anything from a bakery. Slice it warm with a generous spread of butter and you'll wonder why you ever bought a loaf at all.
