Prep: Preheat the oven to 400°F. Line a baking sheet with a silicone baking mat OR with baking parchment and generously flour it.
Mix dry ingredients: Add flour, salt and baking soda to a large mixing bowl. Stir well.
Make dough: Slowly pour in the buttermilk while stirring with your fingers, until you have a sticky dough. Turn it out on the prepared baking sheet and knead it 4-5 times. Shape into a slightly flat circle.
Finish and bake: Sprinkle the top of the bread with flour. Make two deep incisions crosswise through the entire bread (it should look like a four-leaf clover, do cut almost through the bread!). Bake for 30 minutes, or until golden in color and hollow when tapped on the bottom. Cool on a rack before serving warm.
