The overnight mixture of starter, flour and buttermilk develops flavour before it reaches the pan. Baking soda added in the morning helps aerate the acidic batter, creating more bubbles. Fermentation and baking soda work together to make pancakes that are both lightly tangy and fluffy.

Mix the overnight sponge
Mix the starter, buttermilk, flour and sugar in a large bowl. Cover and leave for about 12 hours, or overnight, at cool room temperature, about 18–21°C (65–70°F).
Finish the batter
Beat the eggs with the oil or melted butter. Stir into the sponge just until combined. Add the bicarbonate of soda and salt and stir again. The batter will expand and may start to bubble.
Cook the pancakes
Heat and lightly grease a frying pan or griddle. Add batter in portions of about 59 ml (¼ US cup). When bubbles appear and pop on the surface, turn the pancakes and cook the other side until golden.
Serve
Serve straight away with your favourite toppings, or keep in a warm oven until needed.
Tips
Melted butter can replace the oil in the amount listed in the ingredients.
Storage
Refrigerate leftover pancakes for 1–2 days. Freeze for longer storage.
How to serve
