Preheat the oven to 375 degrees. In a large bowl, combine the dry ingredients with a whisk. Add the buttermilk, eggs, and melted butter and stir with a large wooden or metal spoon until a soft dough forms. Depending on the type of flour you use, you might need to add a little more buttermilk or flour to get the right texture. The dough should stick together easily but isn’t too dry.

Dust a clean countertop with flour and turn the dough out. Knead the dough for 2-3 minutes until smooth and elastic, adding more flour if it’s too sticky. Then, pinch the sides into the center of the dough all around, turn over and rotate several times with both hands at the sides to form a round loaf. Brush the top with more buttermilk and sprinkle with sea salt.

Transfer to a parchment lined baking sheet. With a very sharp knife or razor blade, score the top with a cross pattern. Bake at 375 degrees for about 45 minutes or until it’s golden brown and gives a hollow sound when tapped with the back of a butter knife. Remove from heat and brush all over with melted butter.

Let cool for 10 minutes and serve with soft grass-fed butter.
