In KitchenAid mixer, cream together butter and sugar. Add eggs and beat until well blended.
Combine buttermilk with baking soda in a separate bowl. It will react and puff up so make sure there is plenty of room in the bowl. Stir into the batter.
Fold in cornmeal, flour, and salt until well blended. Pour batter into the prepared tin(s).
Bake until a toothpick inserted in the centre comes out clean. The timing will depend on the size of your baking tin.
Serve plain with chilli or pulled pork. Serve with fresh butter and Honeymakers honey for a brilliant side dish for spicy meals or just on its own with a cuppa.
Notes
If you have a gas hob, you can make this in a cast iron skillet. Melt the butter in the skillet, remove from heat. Stir in sugar then eggs. Continue the recipe at Step 3.
