Preheat the oven to 200c. Grease a 22cm/9-inch square baking pan.

In a large bowl, combine 250ml (1 cup) cornmeal (or polenta), 250ml (1 cup) flour, 65ml (¼ cup) sugar, 1 ½ tsp baking powder, ½ tsp baking soda, and 1 ½ tsp salt.

Whisk together 2 eggs, 250ml (1 cup) buttermilk, and 65ml (¼ cup) melted butter (or rapeseed oil).

Add to the flour mixture and stir till combined (but don’t overmix).

Pour into the pan and bake for around 20-25 minutes till a toothpick comes out clean. Let rest for 15 minutes before serving.
