This quick loaf rises from the reaction between baking soda and cultured buttermilk, so it goes into the oven as soon as the dough comes together. A handful of sunflower seeds brings crunch to its dense, tender crumb. Cut a deep cross in the top to help the center bake through, then cool the loaf before cutting thick slices. Heat oven to 200°C (390°F) and line a tray; whisk flour, baking soda, sugar, salt and sunflower seeds together. Make a well, pour in buttermilk and mix lightly just until no flour remains; do not knead heavily. Form a 17 cm round on the tray and cut a deep cross across the top; brush with beaten egg if using.
